PRBLOCK_IP is a user-friendly MATLAB/SCILAB environment for testing a decomposition interior-point approach for primal block-angular structured problems. Keep in mind is not a production code (an efficient C version is still work to be done). It was developed by Jordi Castro.

To obtain the package just get this file, gunzip and untar it on the directory where PRBLOCK_IP will be installed, and read the README file that will be obtained. The package uses the sparse Cholesky package developed by E. Ng and B. Peyton. The current distribution of PRBLOCK_IP is for Linux systems. For other systems you have to link the Ng-Peyton sparse Cholesky package to MATLAB (see the MATLAB help for details).

You can obtain a description of the algorithm implemented in the package, together with computational results, in this paper .

REMEMBER that you can only use the package for academic purposes. For other types of usage, please contact with the author sending a message to jordi.castroupc.edu.
