* This computation involves a multi-step process. First, the user must allocate \p csrRowPtrC

|
|
* array and computes the total number of non-zeros in \f$C\f$, \p nnzC. The user then allocates both

|
* arrays \p csrColIndC and \p csrValC to have size \p nnzC and calls \p hipsparseXcsrgeam to complete
|
|
* the computation. The desired index base in the output CSR matrix \f$C\f$ is set in the

* \ref hipsparseMatDescr_t \p descrC. See \ref hipsparseSetMatIndexBase().
