InverseFourierCoefficient
InverseFourierCoefficient[expr,n,t]
gives the function of t whose Fourier exponential series representation has coefficients given by expr, where expr is a function of n.
Details and Options
- To use InverseFourierCoefficient, you first need to load the Fourier Series Package using Needs["FourierSeries`"].
- The Fourier exponential series representation used by InverseFourierCoefficient is by default defined to be expr -2πnt.
- InverseFourierCoefficient returns a periodic function of t with default period 1.
- Different choices for the definition of the Fourier exponential series representation can be specified using the option FourierParameters.
- With the setting FourierParameters->{a,b}, the Fourier exponential series representation used by InverseFourierCoefficient is expr -2 πbnt, a periodic function of t with period .
