PLASMA_dtrsmpl - Performs the forward substitution step of solving a system of linear equations after the tile LU factorization of the matrix.

Parameters
[in]NThe order of the matrix A. N >= 0.
[in]NRHSThe number of right hand sides, i.e., the number of columns of the matrix B. NRHS >= 0.
[in]AThe tile factor L from the factorization, computed by PLASMA_dgetrf_incpiv.
[in]LDAThe leading dimension of the array A. LDA >= max(1,N).
[in]descLAuxiliary factorization data, related to the tile L factor, computed by PLASMA_dgetrf_incpiv.
[in]IPIVThe pivot indices from PLASMA_dgetrf_incpiv (not equivalent to LAPACK).
[in,out]BOn entry, the N-by-NRHS right hand side matrix B. On exit, if return value = 0, the N-by-NRHS solution matrix X.
[in]LDBThe leading dimension of the array B. LDB >= max(1,N).
Returns
Return values
PLASMA_SUCCESSsuccessful exit
<0if -i, the i-th argument had an illegal value
