InvMatrix
AnalysisLibErrType InvMatrix (void *inputMatrix, ssize_t matrixSize, void *outputMatrix);
Purpose
Finds the inverse matrix of a square matrix. InvMatrix can perform the operation in place; that is, the input and output matrices can be the same.
If the matrix is singular, InvMatrix returns an error code and does not invert the matrix.

Note If you use this function on an ill-conditioned matrix, the result may be inaccurate due to a loss of precision from arithmetic calculations. The results could also vary between machines because National Instruments uses different optimizations based on processor type. |
Parameters
| Input | ||
| Name | Type | Description |
| inputMatrix | void * | The square matrix to invert. This matrix must be an array of doubles. |
| matrixSize | ssize_t | Number of rows and columns of the input matrix. |
| Output | ||
| Name | Type | Description |
| outputMatrix | void * | Inverse matrix, as an array of doubles. |
Return Value
| Name | Type | Description |
| status | AnalysisLibErrType | A value that specifies the type of error that occurred. Refer to analysis.h for definitions of these constants. |
