FOURIER returns the value by means of Fourier transformation based on a dataset of Fourier coefficients

Syntax

1. FOURIER(Pno%, Ndim%, "ColLab$_1",.., "ColLab$_Ndim%", Xint_1,..,Xint_Ndim%-1)
2. FOURIER(@ObjFn(..), Ndim%, @ObjColPar_1,.., @ObjColPar_Ndim%, Xint_1,..,Xint_Ndim%-1)
3. FOURIER(Telitab$, Ndim%, "ColLab$_1",.., "ColLab$_Ndim%", Xint_1,..,Xint_Ndim%-1)

1. See also Telitab access for a generic description on the use of TeLiTab data
2. Similar to other Data analysis functions, the FOURIER function is a convenient way to interpolate and evaluate data
3. 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:

|FOURIER1|
1
"C"  1.18754E+02
2 "A" "B"
"1" -.73236E+02 .14666E+01
"2" -.10800E+01 .27847E+01
"3" -.13450E+01 -.66913E+00
"4" .74183E+01 .16449E+00
"5" .61982E+01 -.28837E+01|
