Functiondeterminant of an LU decomposed matrix
Syntax C/C++#include <MFstd.h>
float MF_LUdet( fMatrix LU, ui len, int permut );
C++ MatObj#include <OptiVec.h>
void matrix<T>::LUdet( const matrix<T>& MLU, int permut );
Pascal/Delphiuses MFstd;
function MF_LUdet( MLU:fMatrix; len:UIntSize; permut:Integer ): Single;
DescriptionMF_LUdet calculates the determinant of matrix already decomposed into LU form, and return it as a scalar. The argument permut must be +1 or -1, as given by the return value of MF_LUdecompose
