primal-dual interior-point code for linear programming

PCx is a freely available primal-dual interior-point code for linear programming. It implements Mehrotra's predictor-corrector algorithm, the algorithm that forms the basis of most existing interior-point codes for general linear programming. The major computational operation--solution of a linear system with a large, sparse positive definite coefficient matrix--is performed with the sparse Cholesky package of Ng and Peyton (Oak Ridge National Laboratory), with minor modifications to handle small pivot elements. PCx does not solve integer programming problems.

PCx for DEBIAN
----------------------

PCx is configured to use the sparse Cholesky solver of Ng and Peyton,
not the (proprietary) IBM code WSSMP.

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
