Determinant
int status = Determinant (void *inputMatrix, int matrixSize, double *determinant);
Purpose
Finds the determinant of a matrixSize by matrixSize 2D input matrix.
Parameters
Input inputMatrix double-precision 2D
array Input matrix.
matrixSize integer Dimension size of input matrix.
Output determinant double-precision Determinant.
Note: The input matrix must be a matrixSize by matrixSize square matrix.
Return Value
status integer Refer to error codes in
Table 3-2.
Div1D
int status = Div1D (double arrayX[], double arrayY[], int numberofElements,
double outputArray[]);
Purpose
Divides two 1D arrays. The function obtains the ith element of the output array by using the
following formula.
zxy
iii
=/
The function performs the operation in place; that is, outputArray can be the same array as
either arrayX or arrayY.
