numpy.fft.rfft2 — NumPy v1.13 Manual (original) (raw)
numpy.fft. rfft2(a, s=None, axes=(-2, -1), norm=None)[source]¶
Compute the 2-dimensional FFT of a real array.
| Parameters: | a : array Input array, taken to be real. s : sequence of ints, optional Shape of the FFT. axes : sequence of ints, optional Axes over which to compute the FFT. norm : {None, “ortho”}, optional New in version 1.10.0. Normalization mode (see numpy.fft). Default is None. |
|---|---|
| Returns: | out : ndarray The result of the real 2-D FFT. |

Notes
This is really just rfftn with different default behavior. For more details see rfftn.
