LU matrix factorization

C Prototype

extern mxArray *mlfLu(mxArray **U, mxArray **P,
                       mxArray *X, mxArray *thresh);

C Syntax

#include "matlab.h"

mxArray *X;                     /* Required input argument(s) */
mxArray *thresh;                /* Optional input argument(s) */
mxArray *U = NULL, *P = NULL;   /* Optional output argument(s) */
mxArray *L = NULL;              /* Return value */

mlfAssign(&L, mlfLu(&U,NULL,X,NULL));
mlfAssign(&L, mlfLu(&U,&P,X,NULL));
mlfAssign(&L, mlfLu(NULL,NULL,X,NULL));
mlfAssign(&L, mlfLu(NULL,NULL,X,thresh));

MATLAB Syntax

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