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 I am interested in like :

*Improve QR factorization functions, using idea based on CSPARSE cs_dmsol.m
 
*Improve QR factorization by replacing CXSPARSE code with SPQR code, and make the linear solve return 2-norm solutions for ill-conditioned matrices  based on this new code
 
*Implement fourth argument to the sprand and sprandn, and addition arguments to sprandsym that the leading brand implements. (That last one seems to be more a self-TODO-note more than an idea for the student)
 
 
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. Thanks :)
