scipy.fft 链接到 numpy.fft.fftpack.fft 的事实是否记录在案？

Question

我找不到任何关于 scipy.fft 实际上是 link 到 numpy.fft.fftpack.fft 的官方文档。这是一个显示 link:

的 iPython 会话

In [1]: import scipy

In [2]: import numpy

In [3]: scipy.__version__
Out[3]: '0.19.0'

In [4]: numpy.__version__
Out[4]: '1.12.1'

In [5]: scipy.fft
Out[5]: <function numpy.fft.fftpack.fft>

我能找到的关于 scipy.fft 子模块的唯一提及是 this discussion on numpy-discussion and this discussion on SciPy's Github，两者似乎都暗示了这样一个事实，即当时实际上不存在这样的子模块。

Answer 1

scipy.__init__.py 文件有：

from numpy import *
from numpy.random import rand, randn
from numpy.fft import fft, ifft
from numpy.lib.scimath import *

__all__ += _num.__all__
__all__ += ['randn', 'rand', 'fft', 'ifft']

Answer 2

是的，是 documented:

Guidelines for importing functions from Scipy

The scipy namespace itself only contains functions imported from numpy. These functions still exist for backwards compatibility, but should be imported from numpy directly.

Is the fact that scipy.fft links to numpy.fft.fftpack.fft documented anywhere?
