One-dimensional fast Fourier transform

C Prototype

mxArray *mlfFft(mxArray *X, mxArray *n, mxArray *dim);

C Syntax

#include "matlab.h"

mxArray *X;                     /* Required input argument(s) */
mxArray *n, *dim;               /* Optional input argument(s) */
mxArray *null_matrix = NULL;    /* Optional input argument(s) */
mxArray *Y = NULL;              /* Return value */

mlfAssign(&Y, mlfFft(X,NULL,NULL));
mlfAssign(&Y, mlfFft(X,n,NULL));

mlfAssign(&null_matrix, mlfZeros(mlfScalar(0),mlfScalar(0),NULL));
mlfAssign(&Y, mlfFft(X,null_matrix,dim));

mlfAssign(&Y, mlfFft(X,n,dim));

MATLAB Syntax

Y = fft(X)
Y = fft(X,n)
Y = fft(X,[],dim)
Y = fft(X,n,dim)
