Detailed Description

Sparse matrix sparse matrix addition using CSR storage format.

hipsparseXcsrgeam2Nnz computes the total CSR non-zero elements and the CSR row offsets, that point to the start of every row of the sparse CSR matrix, of the resulting matrix C. It is assumed that csr_row_ptr_C has been allocated with size m + 1.

Note

This function is non blocking and executed asynchronously with respect to the host. It may return before the actual computation has finished.

Currently, only HIPSPARSE_MATRIX_TYPE_GENERAL is supported.
