NAME
HPL_pdgesvK1 - Factor an N x N+1 matrix.SYNOPSIS
#include "hpl.h"void HPL_pdgesvK1( HPL_T_grid * GRID, HPL_T_palg * ALGO, HPL_T_pmat * A );
DESCRIPTION
HPL_pdgesvK1 factors a N+1-by-N matrix using LU factorization with row partial pivoting. The main algorithm is the "right looking" variant with 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 algorithmic parameters.
- A (local input/output) HPL_T_pmat *
- On entry, A points to the data structure containing the local array information.
