Module csr 

Compressed Sparse Row (CSR) format.

CSR is the most widely used sparse matrix format. It stores:

• row_ptr[rows+1]: indices into col_idx/values for each row
• col_idx[nnz]: column index for each non-zero
• values[nnz]: the non-zero values

This is the primary format for SpMV, SpMM, and most sparse operations.
