FTGaussian

Generates the Fourier transform of a Gaussian

SYNOPSIS

#include "dip_generation.h"

dip_Error dip_FTGaussian ( output, sigma, volume, cutoff )

DATA TYPES

Output: sfloat, scomplex

FUNCTION

Generates the Fourier transform of a Gaussian with sigma's sigma. (The Fourier transform of a Gaussian, is a Gaussian.) The cutoff variable can be used to avoid the calculation of the exponent of large negative values, which is can be very time consuming. Values below the cutoff are set to zero.
