HPL_pdgesv(3)                HPL Library Functions               HPL_pdgesv(3)

NAME
       HPL_pdgesv - Solve A x = b.

SYNOPSIS
       #include "hpl.h"

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

DESCRIPTION
       HPL_pdgesv factors a N+1-by-N matrix using LU factorization with row
       partial pivoting.  The main algorithm  is the "right looking" variant
       with  or  without 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.
