@ElisR picking up our previous discussion here.
### Problem
It seems that you would like to efficiently evaluate the inverse Wigner transforms for L = N = 64? Are you interested in pushing this t…

Hi @rechmbrs, @fpierfed,
I’ve recently developed an open-source tool that might align with your interests. It’s called FFT Pattern Suppression, and it's designed for automatic detection and removal…

The fast Lomb-Scargle method implemented in ``astropy.stats.LombScargle`` is based on a what is effectively fast nonuniform Fourier transform approximation proposed by Press & Rybicki (1989); the util…

I run gh repo clone FFTW/fftw3
then sh bootstrap.sh and sudo make and sudo make install.
It succesfully installed, then i run dpkg -l 'libfftw3*'
that tells me that 3.3.8 exists on my system (l…

The frequency range is set to be 1~1.8. How can we get these value? It's said that heart rate should located within 0.4 ～ 4 Hz.

Ideas for ECG-based analysis functions will go here. When reading in 12-lead ECGs, should be able to very easily parse them into useful parameters.

### Is your feature request related to a problem? Please describe.
In my research I analyze the damping of oscillations. Generally this would be done using the Fast Fourier Transform (FFT) or the sho…

### Description
I'm experiencing a very poor performance when trying to generate longer noise time series from a PSD. For a month with 5s sampling (about 500k elements), I need to wait already **se…
