Not in GSL. Sparse matrix code tends to be problem-specific, depending on the structure of the matrix and what you want to do with it. I think there are about ten different storage formats that people use, depending on the problem. So you would probably be best to code up the appropriate one for your application to get maximum compression and efficiency. regards Brian Gough
