NAME

HPL_pdgesvK2 - Factor an N x N+1 matrix.

SYNOPSIS

#include "hpl.h"

void HPL_pdgesvK2( HPL_T_grid * GRID, HPL_T_palg * ALGO, HPL_T_pmat * A );

DESCRIPTION

HPL_pdgesvK2 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.
