[source] -
Computes the inverse of
rfft2
.- Parameters
-
-
aarray_like
-
The input array
-
ssequence of ints, optional
-
Shape of the real output to the inverse FFT.
-
axessequence of ints, optional
-
The axes over which to compute the inverse fft. Default is the last two axes.
-
norm{“backward”, “ortho”, “forward”}, optional
-
New in version 1.10.0.
Normalization mode (see
numpy.fft
). Default is “backward”. Indicates which direction of the forward/backward pair of transforms is scaled and with what normalization factor.New in version 1.20.0: The “backward”, “forward” values were added.
