Function

invert a matrix already decomposed into LU form

Syntax C/C++	#include <MFstd.h> void MF_LUinv( fMatrix Inv, fMatrix LU, uVector Ind, ui len );
C++ MatObj	#include <OptiVec.h> void matrix<T>::LUinv( const matrix<T>& MLU, const vector<unsigned>& Ind );
Pascal/Delphi	uses MFstd; procedure MF_LUinv( MInv, MLU:fMatrix; Ind:uVector; len:UIntSize );

Description

MF_LUinv inverts a matrix already decomposed into LU form. Along with the matrix MLU, its permutation indices are needed in the vector Ind as output by MF_LUdecompose
