FW: Announce: semidefinite programming in Octave

[A. Scottedward Hodel]

Linear matrix inequalities have been a popular topic in control systems 
theory since Boyd et al's book LINEAR MATRIX INEQUALTIES IN SYSTEM AND 
CONTROL THEORY was released.  Boyd and Vandenberghe developed a semidefinite
programming package that is on their Stanford website.  I've ported the 
package to Octave, and it is now available at

    ftp://ftp.eng.auburn.edu/pub/hodel/semidef-oct

There are copyright notices, etc., in the code and supporting documentation
that need to be read; in particular, if you use the package in generating
results for a publication, you should give them credit for their package.

To use the package: 
(1) download the code
(2) gunzip -c semidef-oct.tar.gz | tar -xvf -
(3) cd semidef-oct/SRC
(4) make
    (requires mkoctfile from the Octave distribution)
    creates sp.oct, a dynamically loadable function.  Sorry,
    sp is NOT available as an m-file.
(5) An octave demo program called demosp.m is included in the 
    revised sources; you should probably run this first from
    within octave.

Octave is a numerical programming environment; information is available at
