README.mex

To compile the MATLAB interface you need to 

1) Set the CC and FC environment variables appropriately. If you don't have
   a Fortran compiler then you have to use the all C version of PCx.

2) edit mex/Makefile as appropriate. It *should* work ok, assuming you are 
   generally able to compile mex-files. g77 seems to need the f2c libraries
   linked in explicitly, whereas f77 under Solaris does not.

3) Type 'build mex' and you should be all set. You need to be able to compile
   the Ng-Peyton solver supplied with PCx. The scripts should do this for you
   automagically.

4) Add PCx/mex to your MATLABPATH environment. Then, at the MATLAB prompt,
   type 'help PCx' for syntax information. The syntax is virtually identical
   to that of Matlab's linprog (a.k.a. Yin Zhang's LIPSOL).

5) You can test the interface on the supplied datafiles afiro.mat and
   25fv47.mat.
