mlfDel2 (MATLAB C Math Library)

Discrete Laplacian

Minimum number of arguments: one; maximum number: user-defined. Terminate the list of arguments with a NULL.

C Prototype

mxArray *mlfDel2(mxArray *U, ...);

C Syntax

#include "matlab.h"

mxArray *U;            /* Required input argument(s) */
mxArray *hx, *hy, *hz; /* Optional input argument(s) */
mxArray *L = NULL;     /* Return value */

mlfAssign(&L, mlfDel2(U,NULL));
mlfAssign(&L, mlfDel2(U,hx,NULL));
mlfAssign(&L, mlfDel2(U,hx,hy,NULL));
mlfAssign(&L, mlfDel2(U,hx,hy,hz,...,NULL));

MATLAB Syntax

L = del2(U)
L = del2(U,h)
L = del2(U,hx,hy)
L = del2(U,hx,hy,hz,...)
