INPUT

22       flag
23
24              LIS_INS_VALUE
25                     A[i, j] = value
26
27              LIS_ADD_VALUE
28                     A[i, j] = A[i, j] + value
29
30
31              i      The row number of the matrix
32
33
34              j      The column number of the matrix
35
36
37              value  The scalar value to be assigned
38
39
40              A      The matrix

OUTPUT

44       A      The matrix
45

EXIT STATUS

48       The following exit values are returned:
49
50       0      The process is normally terminated
51
52       unspecified
53              An error occurred

NOTE

57       For  the  multiprocessing environment, the i-th row and the j-th column
58       of   the   global   matrix   must   be   specified.     The    function
59       lis_matrix_set_value  stores the assigned value in a temporary internal
60       format. Therefore, after lis_matrix_set_value is called,  the  function
61       lis_matrix_assemble must be called.
