FOURIER returns the value by means of Fourier transformation based on a dataset of Fourier coefficients
Syntax
- FOURIER(Pno%, Ndim%, "ColLab$_1",.., "ColLab$_Ndim%", Xint_1,..,Xint_Ndim%-1)
- FOURIER(@ObjFn(..), Ndim%, @ObjColPar_1,.., @ObjColPar_Ndim%, Xint_1,..,Xint_Ndim%-1)
- FOURIER(Telitab$, Ndim%, "ColLab$_1",.., "ColLab$_Ndim%", Xint_1,..,Xint_Ndim%-1)
...
- See also Telitab access for a generic description on the use of TeLiTab data
- Similar to other Data analysis functions, the FOURIER function is a convenient way to interpolate and evaluate data
- The general format of the Fourier row is:

Examples
The function
ALFA = FOURIER(1, 2, "A", "B", BETA)
with in its data slot information on the Fourier coefficients:
