(a, s=None, axes=- 2, - 1, norm=None)[source]¶ Computes the 2-dimensional inverse FFT of a real array.
- Parameters
- aarrayi_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{None, “ortho”},optional
Normalization mode. By default(None), the transforms are scaled by \(1/n\). It norm is set to “ortho”, the return values will be scaled by \(1/\sqrt{n}\).
- Returns
- outndarray
The result of the inverse real 2-D FFT.
