C Prototype

mxArray *mlfTriu(mxArray *X, mxArray *k);

C Syntax

#include "matlab.h"

mxArray *X;            /* Required input argument(s) */
mxArray *k;            /* Optional input argument(s) */
mxArray *U = NULL;     /* Return value */

mlfAssign(&U, mlfTriu(X,NULL));
mlfAssign(&U, mlfTriu(X,k));

MATLAB Syntax

U = triu(X)
U = triu(X,k)
