Computes the n-dimensional inverse real discrete Fourier transform over designated dimensions of input. The designated dimensions of input are assumed to be the result of IRFFTND. The inner-most dimension contains thefft_length / 2 + 1 unique components of the DFT of a real-valued signal.
If fft_length[i]<shape(input)[i], the="" input="" is="" cropped.="" if="" fft_length[i]="">shape(input)[i], the input is padded with zeros. If fft_length is not given, the default shape(input) is used.</shape(input)[i],>
Axes mean the dimensions to perform the transform on. Default is to perform on all axes.
| Args | |
