# Ported to Octave: $Revision: 2.2 $
SP: Software for semidefinite programming. Can be used to solve
many nonlinear, convex optimization problems. Includes full C source
(which calls LAPACK), which can be used directly or via matlab mex file
interfaces, matlab examples, and documentation.
BETA VERSION. November 1994.
Please be sure to check for updated versions via anon ftp into
isl.stanford.edu, in pub/boyd/semidef_prog.

a copy or modification of this software and in all copies of the
supporting documentation for such software.

CONTENTS:
The FTP directory pub/boyd/semidef_prog at isl.stanford.edu contains
the following files:
- README: this file
- semidef.tar.Z: the package, including all source files and
documentation, but no executable files
- sp.mexds.Z: the executable mex-interface for DECstations
- sp.mex4.Z: the executable mex-interface for SUN4 and Sparcstations
- sp.mexhp7.Z: the executable mex-interface for HP9000/700 workstations
TO INSTALL THE PACKAGE:
1. Move semidef.tar.Z to the directory where you want the code to
live. Then:
your-machine> zcat semidef.tar.Z | tar xvf -
This creates a directory semidef with matlab m-files and two
subdirectories: semidef/SRC (containing C source), and
semidef/DOC (containing a postscript file doc.ps with documentation,
and a copy of the companion survey paper Semidefinite Programming
in compressed postscript).
2. To install the mex-interface on your machine:
- either go to semidef/SRC, edit the Makefile, type make, and
move the compiled mex-file to directory semidef,
- or, if your machine is a DECstation, Sun4 or Sparcstation,
or HP workstation of the 9000/700 series, ftp one of the
executable mex-interface sp.mexXXX.Z, move it to semidef, and
your-machine> uncompress sp.mexXXX
Here `XXX' stands for `ds' if you have a DECstation, `4' if you
have a SUN4 or Sparcstation, or `hp7' if you have an HP.
The documentation and the code are still under development. Please do
not hesitate to send e-mail to vandenbe@esat.kuleuven.ac.be or
boyd@isl.stanford.edu with your comments or questions.
