I need some advice on operations between dense and sparse matrix "objects".
Which operations are possible in scipy ?
Assume that A and B are sparse while C and D are dense matrices of
How about interactions of sparse and dense matrices
- multiplication of a sparse matrix A with a dense matrix C
- Kronecker product of sparse matrices ?
- Kronecker product of a dense and a sparse matrix ?
- sparse matrix functions expm(A),... ?
- sparse eigensolver
- to be continued
Can I use different sparse formats like csc and csr w.r.t. to
And what is the output of A = io.mmread("A.mtx") ? I mean sparse or dense.
Any comments ?
