ifft
Transform iddata objects from frequency to time domain
Syntax
dat = ifft(Datf)
Description
ifft
transforms a frequency-domain iddata
object
to the time domain. It requires the frequencies on Datf
to be equally
spaced from frequency 0 to the Nyquist frequency. This means that if there are
N
frequencies in Datf
and the sample time is
Ts
, then
Datf.Frequency = [0:df:F]
, where F
is
pi/Ts
if N
is odd and
F = pi/Ts*(1-1/N)
if N
is
even.
