INVDFT(R)

Description
This function generates the inverse Discrete Fourier Transform of the range R. Like DFT, 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.

Parameters
R
A range
Examples
0    A      B
1   0.99   0
2   3      6.2
3   4.1   1.1
4   3.3   6.3
With INVDFT(A1..B4) in B6 gives:
      B           C
6    2.8475    3.4
7   -0.8025   -0.2
8   -0.3025   -2.85
9   -0.7525   -0.35

INVDFT(G4..I6) = Error - INVDFT, improper dimensions
