Major changes:

  • Axes support for conv_transform in 1D, 2D and 3D along with corresponding tests

Breaking changes:

  • The new axis or axes argument appears before arguments related to boundary wavelet support. Pywt does not support boundary wavelets, so to respect pywt argument order we have added the new arguments before anything related to boundary wavelets. This makes it easy to migrate from pywt to ptwt and back. Unfortunately, this choice breaks calls to boundary wavelet arguments by order.
    To migrate call arguments related to boundary wavelets by name. This affects only matrix-fwt and wavelet-packet code that uses boundary wavelet support.

Lets take this version for a test drive:

pip install git+ssh://git@github.com/v0lta/PyTorch-Wavelet-Toolbox.git@axis-support

Looks great!

Breaking change. But okay since pywt uses this ordering.
