Operations on sparse matrices

I am currently dealing with sparse matrices and have doubts on whether
we can use
1.) dot (for matrix multiplication) and inv (inverse) operations of
numpy on sparse matrices of CSR format.

I initially constructed my sparse matrix using COO format and then
converted it to CSR format now I want to know whether normal inverse
and matrix multiplications work with sparse csr matrices.

Also can these operations be applied directly to csr matrices

Thanks a lot
