C Syntax

#include "matlab.h"

mxArray *A, *B;             /* Input arguments */
mxArray *C = NULL;          /* Return value */

/* Matrix Arithmetic */
mlfAssign(&C, mlfPlus(A,B));
mlfAssign(&C, mlfMinus(A,B));
mlfAssign(&C, mlfUnaryminus(A));
mlfAssign(&C, mlfUminus(A));
mlfAssign(&C, mlfMtimes(A,B));
mlfAssign(&C, mlfMrdivide(A,B));
mlfAssign(&C, mlfMldivide(A,B));
mlfAssign(&C, mlfMpower(A,B));
mlfAssign(&C, mlfCtranspose(A));

/* Array Arithmetic */
