In my opinion some ideas on the website have very little information. In fact I am interested in sparse matrices as a project for my proposal (taken the idea from the ideas page) but there is almost no explanation of some points like : | In my opinion some ideas on the website have very little information.

I mean, it would be useful to students that maybe have never worked with such algorithms and libraries a brief description of why do you want to perform that changes. In fact I have discover that the cs_dmsol.m function that implements "coarse Dulmage-Mendelsohn decomposition" is already included in the code file "sparse-dmsolve.cc" (am I wrong?). To sum up a more detailed description would be nice, because for you maybe are 15 minutes more of writing but for us are hours of searching.
