lu

LU matrix factorization

C++ Prototype

mwArray lu(const mwArray &X,
           const mwArray &thresh=mwArray::DIN);

mwArray lu(mwArray *U,
           const mwArray &X,
           const mwArray &thresh=mwArray::DIN);

mwArray lu(mwArray *U,
           mwArray *P, 
           const mwArray &X,
           const mwArray &thresh=mwArray::DIN);

C++ Syntax

#include "matlab.hpp"

mwArray X, thresh;          // Input argument(s)
mwArray U, P;               // Output argument(s) 
mwArray L;                  // Return value

L = lu(&U,X);
L = lu(&U,&P,X);
L = lu(X);
L = lu(X,thresh);

MATLAB Syntax

[L,U] = lu(X)
[L,U,P] = lu(X)
lu(X)
lu(X, thresh)
