	* doc/user-ref.html: fixed broken <code> tag

	* mpb-ctl/mpb.c: undid erroneous cleanups (although they wouldn't

	field output for inversion-symmetry case.  We now write the field
	to the file in a few chunks, rather than trying to expand the
	half-complex rfftw output to the full array.  This paves the way
	for a parallel mpbi.  As a side effect, we also circumvent a bug
	in the old makefull routines that caused artifacts to appear in
	the output for 3d cells (reported by Michelle Povinelli).

2001-02-11  Steven G. Johnson  <stevenj@alum.mit.edu>

	* mpb-ctl/mpb.scm.in: Bug fix in combine-band-functions, etcetera,

	src/maxwell/maxwell_pre.c, src/util/mpiglue.h,
	src/util/mpi_utils.c, src/util/mpi_utils.h, tests/eigs_test.c:
	yikes, Allreduce requires sendbuf != recvbuf (although this is not
	clear from the documentation)

	* src/maxwell/maxwell_eps.c: cleanups, fixed calculation of
	eps_inv_mean for MPI

	* src/maxwell/maxwell.c: fixed indenting

	we can't get the number of arguments to a function (apparently)

	* configure.in: fixed gen-ctl-io check, removed AC_PROG_CC_STDC
	ifdef...there's something not working about ifdef that I don't

	* NEWS: clarified the purpose of "nothing"

	* doc/user-tutorial.html, mpb-ctl/examples/tutorial.ctl,
	mpb-ctl/mpb.c: in compute-energy-in-objects, let 'nothing'
	material punch a hole

2001-01-23  Steven G. Johnson  <stevenj@alum.mit.edu>

	* doc/user-ref.html, doc/user-tutorial.html,

	NEWS: added 'nothing' material

	(if?) make check passes

	* mpb-ctl/examples/check.ctl: added sinusoidal Bragg to make check

	* doc/user-ref.html: warn user about run-te and run-tm with
	anisotropic dielectrics

	* NEWS: give credit

	* doc/user-ref.html, mpb-ctl/examples/bragg-sine.ctl,
	mpb-ctl/mpb.c, mpb-ctl/mpb.scm.in, NEWS: added material-function
	type

	* configure.in: don't check for ctl_get_list (not there anymore)

	* doc/installation.html, doc/user-ref.html, NEWS: let's not
	capitalize 'Hermitian'

	* tests/Makefile.in: whoops, fixed $ substitution

	* Makefile.in: changed subdir order in make check

	* Makefile.in, mpb-ctl/Makefile.in, tests/Makefile.in: added 'make

	works with mpbi

	* tests/blastest.out: added sample output

	* tests/maxwell_test.c: allow option to fail if error is too large

	* src/maxwell/maxwell.c: Earlier, we flipped the sign of the G
	vector in order to have a consistent sign of k for mpbi and
	mpbi--it is especially important to be careful about this when you
	have a complex-Hermitian dielectric tensor that breaks (k,-k)
	time-reversal symmetry.  However, this made our planewave basis
	slightly different from before.  It used to be that we had 1 more
	positive-G planewave than negative-G (for even grid sizes), but
	the above change reverses this situation.  It doesn't matter in an
	absolute sense, since the planewave cutoff is still the same, but
	the difference was an annoyance--it caused check.ctl to fail
	because of microscopic changes in the results, and also made us
	inconsistent with the MPB paper.  This change fixes that,
	restoring the +G/-G planewave balance to what it was before
	(although the basis elements are stored in a different order, with
	the -G waves first).

	* src/maxwell/maxwell.c, src/maxwell/maxwell_op.c: fixed G sign
	convention to be consistent for mpbi and mpb

2001-01-11  Steven G. Johnson  <stevenj@alum.mit.edu>

	* mpb-ctl/mpb.scm.in: Modified band-range data functions so that

	/home/stevenj/Repository/mpb/src/matrices/matrices.h: changed flop
	count to double to avoid overflow

	*

2000-11-06  Steven G. Johnson  <stevenj@alum.mit.edu>

	*
	/home/stevenj/Repository/mpb/src/matrices/eigensolver_davidson.c:
	added dead code for alternate computation method of computing
	AY...

	* /home/stevenj/Repository/mpb/src/maxwell/maxwell.h,
	/home/stevenj/Repository/mpb/src/maxwell/maxwell_op.c: added
	maxwell_target_operator1

	* /home/stevenj/Repository/mpb/src/matrices/eigensolver.c: put
	constraint in a more logical place, after the preconditioner.

2000-11-04  Steven G. Johnson  <stevenj@alum.mit.edu>

	* /home/stevenj/Repository/mpb/src/matrices/eigensolver.c: reorder
	iteration output so it's a little less misleading (iteration 1 is
	now after the first eigenvector update, and the last iteration can
	be printed)

2000-10-30  Steven G. Johnson  <stevenj@alum.mit.edu>

	* /home/stevenj/Repository/mpb/tests/normal_vectors.c: use uniform
	directions on a sphere

2000-10-26  Steven G. Johnson  <stevenj@alum.mit.edu>

	* /home/stevenj/Repository/mpb/mpb-ctl/examples/check.ctl: use a
	slightly lower tolerance for the targeted eigensolver

	* /home/stevenj/Repository/mpb/mpb-ctl/examples/check.ctl: updated
	for new MPB...in particular, 3d numbers have changed because of
	the new spherical quadrature, and 2d numbers may have changed
	slightly because of the new handling of the Gamma points.  Also
	fixed some bugs where some of the tests that I had blithely
	inserted conflicted with one another.

	* /home/stevenj/Repository/mpb/doc/user-ref.html,
	/home/stevenj/Repository/mpb/mpb-ctl/mpb.c,
	/home/stevenj/Repository/mpb/mpb-ctl/mpb.scm.in: changed default
	block size, made more flexible

	* /home/stevenj/Repository/mpb/mpb-ctl/mpb.c: print a message to
	remind the user when we're assuming inversion symmetry

	* /home/stevenj/Repository/mpb/mpb-ctl/mpb.c: fixed bug in
	integration (eps_mean, energy in object, etcetera) when using
	inversion symmetry.  Because of the funny format output by real
	FFTs, the fields stored are slightly *over* half of the full
	"logical" arrays.  One has to be careful not to overcount the
	boundary points.

2000-10-25  Steven G. Johnson  <stevenj@alum.mit.edu>

2000-08-10  Steven G. Johnson  <stevenj@alum.mit.edu>

	* utils/mpb-data.c: Re-mapping (rectangularizing, etcetera) now
	maps the center of the original primitive cell to the center of
	the output.  Also, the -x, -y, and -z lattice multipliers now
	apply to the axes *after* the cell is rectangularized.

2000-07-12  Steven G. Johnson  <stevenj@alum.mit.edu>

	* tests/malloctest.c: added benchmark

	* src/maxwell/maxwell_eps.c, tests/Makefile.in,
	tests/normal_vectors.c, src/maxwell/maxwell.h: Added more
	sophisticated spherical quadrature algorithm for computing normal
	vectors (rather than just using the vertices of an icosahedron).

2000-07-10  Steven G. Johnson  <stevenj@alum.mit.edu>

	* /home/a/stevenj/Repository/mpb/mpb-ctl/examples/check.ctl:
	Updated frequencies to account for changes due to new 12-point
	mesh for normal vectors in 2d.  (This really only affects TE
	states.)  We really need to do a more sophisticated quadrature in
	3d, too; good algorithms are apparently available.

2000-07-09  Steven G. Johnson  <stevenj@alum.mit.edu>

	* /home/a/stevenj/Repository/mpb/tests/eigs_test.c: updated for

	typo

2000-07-03  Steven G. Johnson  <stevenj@alum.mit.edu>

	* /home/a/stevenj/Repository/mpb/src/maxwell/maxwell_eps.c: Use
	finer mesh in 2d for normal vector computation (so as not to break
	90-degree rotational symmetries).  I also need to think about the
	3d mesh, although it seems to be a hard problem there to come up
	with general spherically "symmetric" distributions of 3d points.
	Perhaps some sort of weighted quadrature?

2000-06-14  Steven G. Johnson  <stevenj@alum.mit.edu>

	* /home/a/stevenj/Repository/mpb/src/matrixio/matrixio.c: Yikes!

	* /home/a/stevenj/Repository/mpb/mpb-ctl/mpb.scm.in: Added (index

	/home/a/stevenj/Repository/mpb/src/matrices/Makefile.in: Many
	changes.  Switched to line minimization routine from MINPACK-2,
	thanks to Jorge More.  Added reorthogonalization option to
	eigensolver, and renormalization of D, to combat numerical
	problems.  Added option (not on by default) to dynamically reset
	CG based on convergence history, and also another unused option to
	orthogonalize the first step.  Checked to see if Guile provides a
	sort routine (new in 1.3.4, I think), before using it in
	mpb.scm.in.  (Or should we do this dynamically?)

	Use CHK_MALLOC everywhere.  For one thing, this prevents problems
	when we allocate 0 bytes on systems where malloc(0) returns NULL.

	* mpb-ctl/mpb.scm.in, mpb-ctl/mpb.c: handle num-bands = 0

Wed Dec  1 04:04:48 1999  Steven G. Johnson  <stevenj@alum.mit.edu>

	don't use cg with analytic multimin (multimin screws up cg) (because of
	this, multimin is probably not worth it)

	* tests/maxwell_test.c: got rid of gcc warning

	* mpb-ctl/mpb.c:
	randomize-fields now randomizes both the real and imaginary parts.
	Previously, it just set the imaginary parts to zero (which is fine for
	structures with inversion symmetry, but in general cases I don't see
	any justification for it).

	* src/matrices/eigensolver.c:
	verbose mode now prints out trace on every iteration.

	can fix the convergence.  (Maybe by implementing a generalized
	conjugacy condition for conjugate gradient?)

	* src/matrices/eigensolver.c:
	commented on non-storage of U and YtAYU; also changed iteration counter
	to be 1-based in verbose mode

	* src/matrices/matrices.h, src/matrices/scalar.h, src/matrices/evectmatrix.c, src/matrices/matrices.c, src/matrices/eigensolver.c:
	optimized when matrices are diagonal

	* doc/user-ref.html, mpb-ctl/mpb.scm.in, NEWS:
	added output-copies variable

	* /home/a/stevenj/Repository/mpb/mpb-ctl/mpb.scm.in,
	/home/a/stevenj/Repository/mpb/mpb-ctl/mpb.c: handle num-bands = 0

1999-12-01  stevenj  <stevenj@gil-galad.mit.edu>

	* /home/a/stevenj/Repository/mpb/src/matrices/eigensolver.h:

	tuning

1999-11-30  stevenj  <stevenj@gil-galad.mit.edu>

	* /home/a/stevenj/Repository/mpb/src/matrices/eigensolver.c: don't
	use cg with analytic multimin (multimin screws up cg) (because of
	this, multimin is probably not worth it)

	* /home/a/stevenj/Repository/mpb/tests/maxwell_test.c: got rid of
	gcc warning

	* /home/a/stevenj/Repository/mpb/mpb-ctl/mpb.c: randomize-fields
	now randomizes both the real and imaginary parts.  Previously, it
	just set the imaginary parts to zero (which is fine for structures
	with inversion symmetry, but in general cases I don't see any
	justification for it).

	* /home/a/stevenj/Repository/mpb/src/matrices/eigensolver.c:
	verbose mode now prints out trace on every iteration.

	EIGS_ANALYTIC_MULTIMIN, but don't enable by default until I can

	conjugacy condition for conjugate gradient?)

	* /home/a/stevenj/Repository/mpb/src/matrices/eigensolver.c:

	things up for outputting only a single component of a vector
	field.

	* /home/a/stevenj/Repository/mpb/NEWS: fixed typo

Fri Nov 19 00:45:13 1999  Steven G. Johnson  <stevenj@alum.mit.edu>

	* TODO: updated and cleaned up a bit

	* doc/license.html, doc/user-tutorial.html: noted example ctl
	files

	* mpb-ctl/examples/hole-slab.ctl: output hfield instead of dpwr.

	* mpb-ctl/examples/hole-slab.ctl: added hole-slab example

Thu Nov 18 20:43:17 1999  Steven G. Johnson  <stevenj@alum.mit.edu>

	so that foo.out catches errors.

	* Makefile.in: added 'make dist' target

	* mpb-ctl/mpb.c: explained that hack from 1.32 was to get good
	convergence.

	* mpb-ctl/mpb.c: hack: for some reason I don't comprehend, it is
	necessary to re-randomize the fields before doing a zero-k point,
	at least with the new "analytic" linmin in eigensolver.c.  Hey, it
	works, and it can't do any harm.

	* configure.in: bumped beta version number

	* src/matrices/sqmatrix.c: Added explanatory comment to
	sqmatrix_AeBC, noting the probable relative efficiency of various
	operations.

	* src/matrices/eigensolver.c: tiny fix in comment

	* src/matrices/eigensolver.h, src/matrices/eigensolver.c: Added
	"analytic" line minimization based on exact minimization of
	rigorous expansion of the functional for small displacements
	(truly exact for p=1).  Also cleaned up eigensolver code a bit,
	giving generic names to matrices UYtAYU and Usqrt that were being
	used for lots of random things.

Wed Nov 17 23:56:34 1999  Steven G. Johnson  <stevenj@alum.mit.edu>

	k ~ 0 lowest bands (constant fields), to fix problems with slow
	convergence.

	* src/matrices/eigensolver.c, src/matrices/eigensolver.h,
	mpb-ctl/mpb.c: Added constraint "chaining" utilities.

Tue Nov 16 07:10:08 1999  Steven G. Johnson  <stevenj@alum.mit.edu>

	* src/matrices/eigensolver.c: renamed check variable (don't reuse
	E2--bad style)

	* doc/user-ref.html, doc/user-tutorial.html: noted that 2d grid
	does not mean k is 2d

	* doc/developer.html: <emph> -> <em>, and fixed missing close tag
	(why have I been closing everything with </code>?)

	* mpb-ctl/mpb.c: added missing return statements in error code

Mon Nov 15 23:51:42 1999  Steven G. Johnson  <stevenj@alum.mit.edu>

	* TODO: we can't add HDF4 support because the HDF4 license
	conflicts with the GPL

	* TODO: updated; we now restart CG every 100 iterations

	* mpb-ctl/mpb.c: Use EIGS_VERBOSE flag when run with --verbose.
	We should probably print even more output than we already do with
	this flag.

	* configure.in: Fixed version number.

	* mpb-ctl/mpb.c, mpb-ctl/mpb.scm.in, doc/user-ref.html: Added
	"deterministic?" and "iterations" input and output variables.

	* src/matrices/eigensolver.h, src/util/mpiglue.h,
	src/matrices/eigensolver.c: Periodically print feedback in
	eigensolver, even when EIGS_VERBOSE is not set, if the user is
	kept waiting more than a couple of seconds.  Also, implement
	resetting of CG direction every 100 iters (determined by some
	experimentation with the 5x5 defect).

Fri Nov 12 20:46:38 1999  Steven G. Johnson  <stevenj@alum.mit.edu>

	* photon-ctl/photon.scm.in: Removed begin-time macro (moved it to

	* tests/malloctest.c: DEBUG -> DEBUG_MALLOC

	* src/util/debug_malloc.c, configure.in, src/config.h.in,
	src/util/check.h: split --enable-debug-malloc into separate flag,

	but so what).

Fri Sep 10 23:41:28 1999  Steven G. Johnson  <stevenj@alum.mit.edu>

	* src/matrices/blasglue.c: Reverted changes (which I hadn't meant
	to commit)--passing args as strings doesn't help things on the
	$*@#$ alpha.

	* photon-ctl/Makefile.in: added explanatory comment.

	* configure.in, photon-ctl/Makefile.in: --program-suffix, etcetera
	now work.

	photon-ctl/Makefile.in, photon-ctl/photon.c, Makefile.in, TODO,
	configure.in: Mirrored changes in libctl (which is now installed
	in a central location).  Also, separated CFLAGS from -I flags (so
	that CFLAGS can be overridden more easily).  configure script now
	looks for Guile, libctl.

Fri Sep  3 05:30:10 1999  Steven G. Johnson  <stevenj@alum.mit.edu>

	* doc/installation.html, doc/user-tutorial.html, doc/index.html:
	Slowly building the manual...

Wed Sep  1 23:44:39 1999  Steven G. Johnson  <stevenj@alum.mit.edu>

	* doc/user-tutorial.html, doc/index.html, doc/installation.html,
	doc/introduction.html, doc/license.html, doc/user-ref.html,

Tue Aug 31 22:07:52 1999  Steven G. Johnson  <stevenj@alum.mit.edu>

	* src/maxwell/maxwell.h, src/maxwell/maxwell.c: k vector is passed
	to maxwell function in the basis of the reciprocal lattice
	vectors!

	* src/maxwell/maxwell_op.c: Compute transform with correct sign
	(makes a difference for field output in structures lacking
	inversion symmetry).

	* src/maxwell/maxwell_op.c: fixed comment.

	* src/maxwell/maxwell_op.c: Broke out E/H computations into
	subroutines, to prepare for HDF output and position-space
	calculations.

	* configure.in: Cleaned up a little, and fixed (I think?) order of
	linking BLAS libs.

Mon Aug 30 20:31:20 1999  Steven G. Johnson  <stevenj@alum.mit.edu>

	* photon-ctl/examples/bragg.ctl, photon-ctl/examples/sq-rods.ctl:
	Added a couple of examples (very half-baked at this point).

	* configure.in: Added (untested) checks for BLAS in
	vendor-specific libraries (which, I *think*, include an optimized
	BLAS).

Fri Jul 16 22:20:28 1999  Steven G. Johnson  <stevenj@alum.mit.edu>

	* tests/maxwell_test.c, src/maxwell/maxwell.h,
	src/maxwell/maxwell_op.c, src/maxwell/maxwell_pre.c,
	src/maxwell/maxwell.c: Added in epsilon tensor initialization
	routine, and got rid of eps_inv_mean[band] mess from maxwell_op
	since it wasn't doing any good in the preconditioner.

Thu Jun 10 22:04:23 1999  Steven G. Johnson  <stevenj@alum.mit.edu>

	* tests/maxwell_test.c: Fixed -h help string.

	* configure.in: Checked for ASCII project optimized Pentium Pro

	added tolerance parameter.

	* tests/maxwell_test.c: Whoops!  TWOPI is a double, not

Fri Jun  4 23:14:43 1999  Steven G. Johnson  <stevenj@alum.mit.edu>

	* tests/maxwell_test.c: Default to quarter-wave stack.

	* tests/maxwell_test.c, src/maxwell/maxwell.h,
	src/maxwell/maxwell_op.c, src/maxwell/maxwell_pre.c,
	src/matrices/eigensolver.c, src/matrices/eigensolver.h,
	src/maxwell/maxwell.c: Added code to find maxwell eigenvals
	"targeted" around a particular frequency.  The convergence is
	slower than I would like, though.

	* src/maxwell/maxwell_pre.c: For now, don't subtract eigenvals
	from the preconditioner, as least not until I understand the
	effects better.  (Right now, seems to make convergence worse in
	many cases, and also seems to mess up the convergence criteria for
	the higher bands.)

Tue Jun  1 19:59:38 1999  Steven G. Johnson  <stevenj@alum.mit.edu>

	* src/config.h.in, src/maxwell/maxwell.h, configure.in: Updated to
	work with [ds]?r?fftw libraries (aren't regular expressions
	wonderful?).

	op and preconditioner into their own files.

Thu Feb  4 02:51:19 1999  Steven G. Johnson  <stevenj@alum.mit.edu>

	* src/maxwell/maxwell.c, TODO: Check for k == 0 in when setting k
	vector.

	* TODO, src/matrices/eigensolver.c: Added stricter convergence
	(convergence of each eigenvalue separately).

	* tests/maxwell_test.c: Small fixes.

	* tests/eigs_test.c, tests/maxwell_test.c, src/maxwell/maxwell.c,
	src/maxwell/maxwell.h, src/matrices/eigensolver.c,

	between TE and TM modes.

Wed Feb  3 22:55:15 1999  Steven G. Johnson  <stevenj@alum.mit.edu>

	* src/config.h.in, tests/maxwell_test.c, configure.in: Added
	--enable-prof.

	* tests/maxwell_test.c, src/maxwell/maxwell.c,
	src/maxwell/maxwell.h, tests/eigs_test.c,
	src/matrices/eigensolver.h, src/matrices/eigensolver.c, TODO: Lots
	of changes to eigensolver routine and preconditioners, yielding
	dramatic improvements in convergence.  The most important thing
	new is that we now diagonalize the subspace on each iteration of
	eigensolver.  This makes the preconditioner much more sensible,
	and also allows us to subtract the eigenval from the
	preconditioner (a better approximation, hopefully, to the correct
	Hessian).

Sun Jan 31 07:49:01 1999  Steven G. Johnson  <stevenj@alum.mit.edu>

	* src/maxwell/maxwell.c, src/maxwell/maxwell.h: No need to store
	k+G in k_data since we don't use this information.

	* tests/maxwell_test.c, TODO, src/maxwell/maxwell.c: Maxwell seems
	like it might be working!

Sat Jan 30 22:17:11 1999  Steven G. Johnson  <stevenj@alum.mit.edu>

	* src/matrices/scalar.h, tests/eigs_test.c: Made complex
	eigenvector output in eigs_test more uniform.

	* tests/Makefile.in: Whoops!  make clean should delete
	eigs_test.o.

	* tests/maxwell_test.c, src/maxwell/maxwell.h, src/util/check.h,
	src/util/debug_malloc.c, tests/Makefile.in,
	src/matrices/eigensolver.c, src/maxwell/maxwell.c, Makefile.in,
	TODO, configure.in, src/config.h.in: Fixed uninitialized D bug in
	eigensolver.c (doh!).  Added test for maxwell operator code, and
	got maxwell closer to working (I hope).

	config.sub, configure.in, install-sh, Makefile.in:
	"Autoconfiscated" everything (i.e. adapted for use with GNU
	autoconf portability tools).

	* src/matrices/scalar.h: Separate scalar_complex type that is
	always defined.

	* src/maxwell/maxwell.c, src/maxwell/maxwell.h,

	linear.

	* tests/eigs_test.c, src/matrices/eigensolver.c,
	src/matrices/eigensolver.h: Added callback data pointer to
	eigensolver.

Sat Aug  8 19:18:06 1998  Steven G. Johnson  <stevenj@alum.mit.edu>

	* src/util/fortranize.h, src/matrices/Attic/fortranize.h: Moved
	fortranize.h to util directory.

	* tests/Attic/Makefile: Makefile for test programs.  This will
	probably get replaced by something autoconf'y later, but it will
	do for now.

	* tests/blastest.c: Check for memory leaks at end.

	* tests/eigs_test.c: Only print out A for n <= 10 instead of 20.

	* src/matrices/eigensolver.c: Increased iteration limit and
	included it in the failure message.

	sqmatrix_copy.

	* tests/eigs_test.c: Got things working.
