rfft2
(a, s=None, axes=- 2, - 1, norm=None)[ソース]¶ Computes the 2-dimensional FFT of a real array.
- Parameters
- aarray
Input array, taken to be real.
- ssequence of ints, optional
Shape of the FFT.
- axessequence of ints, optional
Axes over which to compute the FFT.
- norm{None, "ortho"},optional
Normalization mode. By default(None), the transforms are unscaled. It norm is set to "ortho", the return values will be scaled by \(1/\sqrt{n}\).
- Returns
- outndarray
The result of the real 2-D FFT.
