HPL_pdgesvK1(3)              HPL Library Functions             HPL_pdgesvK1(3)


HPL_pdgesvK1 - Factor an N x N+1 matrix.


#include "hpl.h" void HPL_pdgesvK1( HPL_T_grid * GRID, HPL_T_palg * ALGO, HPL_T_pmat * A );


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.


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.
