HPL_pdgesvK2 - Factor an N x N+1 matrix.
#include "hpl.h"
void HPL_pdgesvK2( HPL_T_grid * GRID,
HPL_T_palg * ALGO, HPL_T_pmat * A );
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.
- 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.
