HI, I spent some time looking over the guided_a3c example, documentation and reading the code for the BTgymRandomDataDomain class, and my question is: if I want to use pandas.resample() function and d…

The description of the pywt.dwt_max_levels function seems ambiguous to me.
```
Compute the maximum useful level of decomposition.

I have noticed that discrete wavelet transform using Haar wavelet does not really match up results given by Mathematica.
For example Haar DWT of sequence {1,2,3,4} gives {3.5355, 3.5355, -0.7071, 2…

It seems that the Hamiltonians produced by `plane_wave_external_potential` and `dual_basis_external_potential` are non-Hermitian if the number of grid subdivisions is even and any atoms are not at the…

Currently, the EMC Global VX includes a section where a Fourier Decomposition is applied to fields like Geopotiential Height prior to the computation of continuous statistics. Similar to Wavelet-Stat…

For various combinations of image size and number of resolutions, with default settings i.e. mathematically lossless, image resulting from round trip encode/decode does not equal original. See issue…

WavletPacket2D constructor when called as:
```
import pywt
import numpy as np
img = np.random.random((200, 200))
wp = pywt.WaveletPacket2D(img, wavelet='db1', level=
