[SciPy-user] Invert a sparse matrix
Thu Oct 4 06:56:27 CDT 2007
Is there any function to invert a sparse matrix, giving a sparse result?
I couldn't find much information on this.
Also how does one do sparse matrix-vector multiplication? The resulting
vector doesn't need to be sparse, but it's important the multiplication is
done without converting the array/matrix to full form (not enough ram).
I will have a very large matrix, that must remain sparse to fit in memory,
and I need to use it for some basic operations (matrix-vector multiplication
by itself and it's inverse).
Thanks for your help,
