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.
