NFourierTransform[expr, t, ] gives a numerical approximation to the Fourier transform of expr evaluated at the numerical value , where expr is a function of t.
The numerical approximation to the Fourier transform of expr is by default defined to be .
Different choices for the definition of the Fourier transform can be specified using the option FourierParameters.
With the setting FourierParameters->{a, b}, the Fourier transform computed by NFourierTransform is .
The parameter b in the setting FourierParameters->{a, b} must be numeric.
In addition to the option FourierParameters, NFourierTransform can also accept the options available to NIntegrate. These options are passed directly to NIntegrate.
