SJSU Singular Matrix Database

SJsingular -- MATLAB toolbox for managing the SJSU Singular Matrix Collection:

SJsingular is a MATLAB toolbox for managing the SJSU Singular Matrix Database. Most users will not need the SJsingular package. It is available for download so that users can see how the matrices were created and to facilitate the package development.

SJsingular is a derivative work based on the UFcollection toolbox from SuiteSparse by Timothy Davis. Initial modifications to UFcollection were done by Nikolay Botev at San Jose State University.

To install the SJsingular toolbox it is necessary to first install SuiteSparse. Next download and uncompress the appropriate SJsingular file (below), move from inside Matlab 7.0 or higher to the SJsingular folder and then type SJdownload. This will set the Matlab path and will download the current collection of matrices.
