[SciPy-dev] FE+sparse utilities

Hi,

often, people ask here how to quickly assemble small dense matrices into 
a global sparse matrix in the finite element sense. I have made a small 
package that could help with this task (BSD license, so that it could be 
included in scipy, if there is interest). It works directly with CSR 
sparse matrices and the whole matrix structure is preallocated prior to 
assembling -> no conversion overhead.

It is available at http://147.228.107.66/mymoin/SFE. Note that this is a 
very preliminary web site on my work computer, so it may be down 
occasionally (especially during weekends :)).

I would greatly appreciate any feedback,
r.
