HPL_pdgesv(3) HPL Library Functions HPL_pdgesv(3)## NAME

HPL_pdgesv - Solve A x = b.## SYNOPSIS

#include"hpl.h"voidHPL_pdgesv(HPL_T_grid*GRID,HPL_T_palg*ALGO,HPL_T_pmat*A);## DESCRIPTION

HPL_pdgesvfactors 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.## SEE ALSO
