integer(kind(hipsparse_status_success)) function	hipsparsexcsrsm2_zeropivot_ (handle, myInfo, position)

Detailed Description

Sparse triangular system solve using CSR storage format.

hipsparseXcsrsm2_zeroPivot returns HIPSPARSE_STATUS_ZERO_PIVOT, if either a structural or numerical zero has been found during hipsparseXcsrsm2_analysis() or hipsparseXcsrsm2_solve() computation. The first zero pivot \(j\) at \(A_{j,j}\) is stored in position, using same index base as the CSR matrix.

position can be in host or device memory. If no zero pivot has been found, position is set to -1 and HIPSPARSE_STATUS_SUCCESS is returned instead.

Note

hipsparseXcsrsm2_zeroPivot is a blocking function. It might influence performance negatively.
