PyWavelets 0.5.2 Release Notes

PyWavelets 0.5.2 is a bug-fix release with no new features compared to 0.5.1.

Bugs Fixed

The pywt.data.nino data reader is now compatible with numpy 1.12. (#273)

The wp_scalogram.py demo is now compatibile with matplotlib 2.0. (#276)

Fixed a sporadic segmentation fault affecting stationary wavelet transforms of multi-dimensional data. (#289)

idwtn now treats coefficients set to None to be treated as zeros (#291). This makes the behavior consistent with its docstring as well as idwt2. Previously this raised an error.

The tests are now included when installing from wheels or when running python setup.py install. (#292)

A bug leading to a potential RuntimeError was fixed in waverec. This bug only affected transforms where the data was >1D and the transformed axis was not the first axis of the array. (#294).
