PLASMA_strsmpl - Performs the forward substitution step of solving a system of linear equations after the tile LU factorization of the matrix.
- Parameters:
-
[in] | N | The order of the matrix A. N >= 0. |
[in] | NRHS | The number of right hand sides, i.e., the number of columns of the matrix B. NRHS >= 0. |
[in] | A | The tile factor L from the factorization, computed by PLASMA_sgetrf. |
[in] | LDA | The leading dimension of the array A. LDA >= max(1,N). |
[in] | L | Auxiliary factorization data, related to the tile L factor, computed by PLASMA_sgetrf. |
[in] | IPIV | The pivot indices from PLASMA_sgetrf (not equivalent to LAPACK). |
[in,out] | B | On entry, the N-by-NRHS right hand side matrix B. On exit, if return value = 0, the N-by-NRHS solution matrix X. |
[in] | LDB | The leading dimension of the array B. LDB >= max(1,N). |
- Returns:
- Return values:
-
| PLASMA_SUCCESS | successful exit |
| <0 | if -i, the i-th argument had an illegal value |
