FOURIER SERIES PACKAGE SYMBOL
NInverseFourierTransform
gives a numerical approximation to the inverse Fourier transform of expr evaluated at the numerical value t, where expr is a function of
.
DetailsDetails
- To use
, you first need to load the Fourier Series Package using Needs["FourierSeries`"]. - The numerical approximation to the inverse Fourier transform of expr is by default defined to be
NIntegrate[expr
-
t, {
, -∞, ∞}]. - 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
is
NIntegrate[expr
-
b
t, {
, -∞, ∞}]. - The parameter b in the setting FourierParameters->{a, b} must be numeric.
- In addition to the option FourierParameters,
can also accept the options available to NIntegrate. These options are passed directly to NIntegrate.
