[SciPy-User] fancy indexation of sparse matrices is terrible slow

thank you, it work very well now for both M and M.T  
Doesn't anyone know when next scipy/numpy releases are planned (approximately, of course)?  
Thank you in advance, D.  
  
  I looked at the CSR fancy indexing code and realized it was much worse  
than I originally thought so I implemented a faster path in C++ for  
the operation. With SciPy r6139 (  
http://projects.scipy.org/scipy/changeset/6139 ) I get a considerable  
improvement with a variation of your example
