NAME

6       HPL_pdgesv0 - Factor an N x N+1 matrix.
7

SYNOPSIS

9       #include "hpl.h"
10
11       void  HPL_pdgesv0( HPL_T_grid * GRID, HPL_T_palg * ALGO, HPL_T_pmat * A
12       );

DESCRIPTION

15       HPL_pdgesv0 factors a N+1-by-N matrix using LU factorization  with  row
16       partial  pivoting.   The main algorithm  is the "right looking" variant
17       without look-ahead. The lower triangular factor is left  unpivoted  and
18       the  pivots  are not returned. The right hand side is the N+1 column of
19       the coefficient matrix.

ARGUMENTS

22       GRID    (local input)           HPL_T_grid *
23               On entry,  GRID  points  to the data structure  containing  the
24               process grid information.
25
26       ALGO    (global input)          HPL_T_palg *
27               On  entry,   ALGO  points to  the data structure containing the
28               algorithmic parameters.
29
30       A       (local input/output)    HPL_T_pmat *
31               On entry, A points to the data structure containing  the  local
32               array information.
