lis_matrix_set_value - Man Page
assign the scalar value to the element of the matrix
Synopsis
#include "lis.h"
LIS_INT lis_matrix_set_value(LIS_INT flag, LIS_INT i, LIS_INT j, LIS_SCALAR value, LIS_MATRIX A);
Description
Assign the scalar value to the (i, j)-th element of matrix A.
Input
- flag
- LIS_INS_VALUE
A[i, j] = value
- LIS_ADD_VALUE
A[i, j] = A[i, j] + value
- i
The row number of the matrix
- j
The column number of the matrix
- value
The scalar value to be assigned
- A
The matrix
Output
- A
The matrix
Exit Status
The following exit values are returned:
- 0
The process is normally terminated
- unspecified
An error occurred
Note
For the multiprocessing environment, the i-th row and the j-th column of the global matrix must be specified. The function lis_matrix_set_value stores the assigned value in a temporary internal format. Therefore, after lis_matrix_set_value is called, the function lis_matrix_assemble must be called.
