DFT

Syntax: DFT(R)

R = a range representing a vector

DFT generates the Discrete Fourier Transform of the given range R. R must represent a real vector (either its row or column dimension must be 1), or a complex vector (either its row or column dimension must be 2). The result is always a complex vector.

Example:

Vector C1..C4 =

  C
1 1.2
2 3.4
3 54.3
4 0.34
   

DFT(C1..C4) =
59.2 0
-53.1 3.06
51.8 0
-53.1 -3.06
