MatrixDet

MatrixDet (dataMatrix)​

The MatrixDet function returns the determinant of dataMatrix. The matrix wave must be a real, square matrix or else the returned value will be NaN.

Details​

The function calculates the determinant using LU decomposition. If, following the decomposition, any one of the diagonal elements is either identically zero or equal to 10^-100, the return value of the function will be zero.
