NAME

lis_matrix_set_size - assign the size of the matrix

SYNOPSIS

#include "lis.h"

LIS_INT lis_matrix_set_size(LIS_MATRIX A, LIS_INT local_n, LIS_INT global_n);

DESCRIPTION

Assign the size of matrix A.

INPUT

A: The matrix
local_n: The number of rows of the partial matrix
global_n: The number of rows of the global matrix

EXIT STATUS

The following exit values are returned:

0: The process is normally terminated
unspecified: An error occurred

NOTE

Either local_n or global_n must be provided. In the case of the serial and multithreaded environments, local_n is equal to global_n. Therefore, both lis_matrix_set_size(A,n,0) and lis_matrix_set_size(A,0,n) create a matrrix of size n x n. For the multiprocessing environment, lis_matrix_set_size(A,n,0) creates a partial matrix of size n x N on each processing element, where N is the total sum of n. On the other hand, lis_matrix_set_size(A,0,n) creates a partial matrix of size m_p x n on the processing element p. The values of m_p are determined by the library.
