NInverseFourierTransform

NInverseFourierTransform[expr, Omega, t]
gives a numerical approximation to the inverse Fourier transform of expr evaluated at the numerical value t, where expr is a function of Omega.
  • The numerical approximation to the inverse Fourier transform of expr is by default defined to be .
  • Different choices for the definition of the inverse Fourier transform can be specified using the option FourierParameters.
  • With the setting FourierParameters->{a, b}, the inverse Fourier transform computed by NInverseFourierTransform is .
