KmlIssCgInit?I
Initialize the data structure and associate the coefficient matrix provided by the user to the solution system.
Interface Definition
C interface:
int KmlIssCgInitSI(KmlSolverTask **handle, int n, const float *a, const int *ja, const int *ia);
int KmlIssCgInitDI(KmlSolverTask **handle, int n, const double *a, const int *ja, const int *ia);
Parameters

Type |
Description |
Input/Output |
|---|---|---|---|
handle |
KmlSolverTask ** |
Solver handle. The handle cannot be a null pointer. |
Input/Output |
n |
int |
Dimension of matrix A |
Input |
a |
|
Array whose dimension is the quantity of non-zero elements. a[i] is the value of the ith non-zero element. The lifecycle of this array is the same as that of the handle. |
Input |
ja |
int * |
Array whose dimension is the quantity of non-zero elements. ja[i] is the column number of the ith non-zero element. The lifecycle of this array is the same as that of the handle. |
Input |
ia |
int * |
(n+1)-dimensional array. ia[i] is the index of the first non-zero element in the ith row in all non-zero elements. The lifecycle of this array is the same as that of the handle. |
