cupy.fft.irfft2¶
-
cupy.fft.
irfft2
(a, s=None, axes=(- 2, - 1), norm=None)[source]¶ Compute the two-dimensional inverse FFT for real input.
- Parameters
a (cupy.ndarray) – Array to be transform.
s (None or tuple of ints) – Shape of the output. If
s
is not given, they are determined from the lengths of the input along the axes specified byaxes
.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. Ifs
is not given, the length of final transformed axis of output will be 2*(m-1) where m is the length of the final transformed axis of the input.- Return type
