Thu Apr 19 00:31:36 1990 Aubrey Jaffer (jaffer at lammert)

fixed and added many functions.
Wed Apr 18 17:22:31 1990 Aubrey Jaffer (jaffer at lammert)
* seval.l (fcexpt):

fcinverse works but negates its argument (why?).
Mon Apr 16 01:21:49 1990 Aubrey Jaffer (jaffer at lammert)
* ext (ext_clear-denoms):
works for square roots. subtle problem with determinant screws up
higher order.
* syntax -> macsyma.syn
* meta -> builtins :
documentation strings entered for most functions.
* poly (sylvester & bruno) :
resultant matrix functions created.
Wed Apr 11 01:37:54 1990 Aubrey Jaffer (jaffer at lammert)

functions. Problems with inverses.
* radicals :
radicands now come out positive.
Thu Apr 5 01:02:04 1990 Aubrey Jaffer (jaffer at lammert)
* radicals, matrix, types (make-rat):
created in types. This eliminates almost all constructions:
(list @ num -denom)

schemized. improved ipow. radicands keep coming out negative.
Wed Apr 4 15:48:20 1990 Aubrey Jaffer (jaffer at lammert)
* syntax (leadingplus => leading+?)
fixed and moved to seval
* syntax (inprint)
now understands (define var exp)
Fri Mar 30 01:24:04 1990 Aubrey Jaffer (jaffer at lammert)
* cgol, seval (math):
input and output grammar independently settable. grammars now
contain both input and output functions. line terminators work
correctly.
Thu Mar 29 00:31:20 1990 Aubrey Jaffer (jaffer at gerber)
* cgol, syntax, seval:
made input syntax switchable. Input delimiters made postfix (this
was a change to cgol_parse).
Wed Mar 28 16:16:25 1990 Aubrey Jaffer (jaffer at lammert)
* cgol (all):
all syntax tables now in one structure: cgol_grammar.
* seval, syntax, cgol (seval, bunch->sexp, inprint, #\[):
sexps now use vectors instead of '(bunch ...) to represent vectors.
delimiters for end of expression (#\; #\$) now are read after the
expression is read and dispatched in seval. This should move to cgol.
Tue Mar 27 00:19:21 1990 Aubrey Jaffer (jaffer at gerber)
* poly, types, seval:
leading coefficient of impls is now negative. this means less
poly_negates for type conversion.

simplified
Tue Mar 20 00:08:31 1990 Aubrey Jaffer (jaffer at lammert)
* poly.lisp (degree&lc):
eliminated in favor of much simpler degree. This sidesteps Common
Lisp compiler problem. It also means lc is not contructed unless
it is needed. Should speed things up.
* scl.scm:
read-file removed (was interfering with reader). Many common lisp
utility functions defined.
* syntax.l:
"|" eliminated from symbol names. Scheme association lists now
used.
* factor.l (poly_factor-split):
do* eliminated.
* matrix.l (mtrx_diagmatrix, rank, triangularize):
do* eliminated
* poly.l (poly_coeff):
rewritten to not use do*. map-no-end-0s written; gives much more
efficient implementation of poly_coeff. Everything using
univ_monomial should be rewritten using map-no-end-0s.
* scl.lisp (define):
defun removed; Less error messages on loading. Non-scheme
functions removed. List? fixed to accept '(). pair?, list? and
procedure? now check for closures-might-be-conses.

name with them. Still cannot compile poly.lisp.
