lis_matrix_set_size - Man Page
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.
