`scipy.signal._signaltools:_init_freq_conv_axes`

source: /scipy/signal/_signaltools.py :426

Signature

   def     _init_freq_conv_axes (    in1    ,    in2    ,    mode    ,    axes    ,    sorted_axes    =  False     )

Summary

Handle the axes argument for frequency-domain convolution.

Extended Summary

Returns the inputs and axes in a standard form, eliminating redundant axes, swapping the inputs if necessary, and checking for various potential errors.

Parameters

in1 : array: First input.
in2 : array: Second input.
mode : str {'full', 'valid', 'same'}, optional: A string indicating the size of the output. See the documentation fftconvolve for more information.
axes : list of ints: Axes over which to compute the FFTs.
sorted_axes : bool, optional: If True, sort the axes. Default is False, do not sort.

Returns

in1 : array: The first input, possible swapped with the second input.
in2 : array: The second input, possible swapped with the first input.
axes : list of ints: Axes over which to compute the FFTs.
