mars.tensor.fft.rfft2¶

mars.tensor.fft.rfft2(a, s=None, axes=(- 2, - 1), norm=None)[源代码]¶

Compute the 2-dimensional FFT of a real tensor.

参数

a (array_like) – Input tensor, 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) – Normalization mode (see mt.fft). Default is None.

返回

out – The result of the real 2-D FFT.

返回类型
