cupy.fft.rfft2¶
-
cupy.fft.
rfft2
(a, s=None, axes=(- 2, - 1), norm=None)[source]¶ Compute the two-dimensional FFT for real input.
- Parameters
a (cupy.ndarray) – Array to be transform.
s (None or tuple of ints) – Shape to use from the input. If
s
is not given, the lengths of the input along the axes specified byaxes
are used.axes (tuple of ints) – Axes over which to compute the FFT.
norm (None or
"ortho"
) – Keyword to specify the normalization mode.
- Returns
The transformed array which shape is specified by
s
and type will convert to complex if the input is other. The length of the last axis transformed will bes[-1]//2+1
.- Return type
