InverseFourierCoefficient


gives the function of t whose Fourier exponential series representation has coefficients given by expr, where expr is a function of n.
MORE INFORMATION
  • The Fourier exponential series representation used by is by default defined to be .
  • 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, the Fourier exponential series representation used by is , a periodic function of t with period .
