ok thanks for the info I'll stick to using PySparse then as a user I have a request for a n-d sparse array class and not only 2d-matrix with possibility to take slices like in an ordinary nd array I have more or less built such a class based on PySparse if that can be of any interest thanks P ----- Original Message ----- From: "Travis Oliphant" <oliphant@ee.byu.edu> To: "SciPy Users List" <scipy-user@scipy.net> Sent: Monday, April 26, 2004 11:46 PM Subject: Re: ***[Possible UCE]*** [SciPy-user] no __setitem__ in spmatrix class

Hi

I noticed there is no __setitem__ method in spmatrix class in scipy.sparse module but what if one needs to (sparsely) fill the matrix after __init__ time ?

The sparse matrix module is currently incomplete. In a few days it should be much better (hopefully for Scipy 0.3.1). Apparently matrix multiplication is not working (don't know why as it uses sparsekit). Right now what does work is to use the dictmatrix type to build up a matrix and then use lu_factor and or solve to solve the linear system (I've been using that quite a bit).

Things should be much better for sparse in a little while.
