This is some work I did as part of a research project at the end of my bachelors studies. There's nothing really new here, just an implementation of plsi for sparse matrices. My advisor for the project was Dr. Tim Davis, the creator of many of MATLAB's sparse matrix algorithms. My project is a small extension of his library and therefore obviously has a dependency on CSparse/CXSparse. I haven't touched this code since early 2010, so I don't quite remember the details on how it all works. See cs_plsi.m for a short example on how to use this properly. Also see the documentation in cs_plsi.c for more information. Many thanks to Dr. Tim Davis (http://www.cise.ufl.edu/~davis/) for the help while writing this. You can see two matrices which I used this on here: http://www.cise.ufl.edu/research/sparse/matrices/Buss/index.html Please see INSTALL for installation instructions.
