<Result> = MatDeterminant(<Matrix>)
<Result>: Real
Determinant of matrix. The determinant of matrix is null if this value is equal to 0.
<Matrix>: Character string
Name of the matrix to be used, defined with MatCreate.
Remarks

Matrix existence

The matrix existence is not checked. To check the matrix existence, use MatExist.

Managing errors

Caution: MatDeterminant returns no error code. To find out whether errors have been generated when calculating the determinant, use MatError. To get the details of the error, use ErrorInfo with the errMessage constant.
Business / UI classification: Neutral code
