I've been using Mike Marino's ISWT routine with PyWavelets 0.2.2 for quite a while now. The function made it to PyWavelets 0.4.0, but its performance is significantly slower than with 0.2.2.
I extrac…

why does pywt.dwt(np.arange(8),'db2') return two arrays of size 5 each? As far as I understand the DWT should always do a downsampling of size 2, no matter the length of the filter... Am I missing som…

In my subfield (signal processing), it's common to see the full level wavelet transforms represented in a single array. This adds indexing ease and wavelet transforms tend to be treated as complete ar…

Hello everybody and thanks for this great library.
I'm newbie in wavelets and have a question regarding SWT. I don't know if it's a bug or not, but why do I get some weird spikes at the end of sequenc…

I would like to use the [CDF 9/7 wavelets](https://en.wikipedia.org/wiki/Cohen-Daubechies-Feauveau_wavelet) on a 1D signal. This is the test code I have, which doesn't work (i.e. the reconstructed sig…

The following two snippets of code should be equivalent, I think:
```
import numpy as np
import pywt
a = np.random.randn(64,64)
w = pywt.Wavelet('bior3.3')
#w = pywt.Wavelet('db2')
#w = pywt.Wavelet…

When browsing the Fasti periodization, there are two date types: BC dates from a semi-formal Ukrainian periodization, and BP (2000) dates from the main periodization in use on the site. The BP dates …

Currently the client lists the periodizations by title, but this is both awkward (some of the titles for the web-based versions are not very informative) and not the way specialists are likely to find…
