I am looking for the best package for sparse matrix multiplication on single core solution. I am not looking for CUDA, MPI or OpenMP solutions.

My preference for languages in decreasing order : Matlab, Python, C/C++.

Matlab has its own matrix multiplication function which can be used for sparse matrix multiplication. But are there any better package(s) available ?

I have to multiply two large matrices which are in sparse format.

Eg., one matrix is 677000-by-48000 and another is 48000-by-8192. Here, n-by-d means n : # of rows, d : # of columns

I'm no expert for sparse matrices but I do know the renowned 'eigen' C++ library.

They have a tutorial on sparse matrices, reachable from the documentation page.
