HPL_pdgesv0(3) HPL Library Functions HPL_pdgesv0(3) NAME HPL_pdgesv0 - Factor an N x N+1 matrix. SYNOPSIS #include "hpl.h" void HPL_pdgesv0( HPL_T_grid * GRID, HPL_T_palg * ALGO, HPL_T_pmat * A ); DESCRIPTION HPL_pdgesv0 factors a N+1-by-N matrix using LU factorization with row par- tial pivoting. The main algorithm is the "right looking" variant without look-ahead. The lower triangular factor is left unpivoted and the pivots are not returned. The right hand side is the N+1 column of the coefficient matrix. ARGUMENTS GRID (local input) HPL_T_grid * On entry, GRID points to the data structure containing the process grid information. ALGO (global input) HPL_T_palg * On entry, ALGO points to the data structure containing the algo- rithmic parameters. A (local input/output) HPL_T_pmat * On entry, A points to the data structure containing the local array information.
