CWT and Scalogram

[alejandro...@gmail.com]

Dear PyWavelets team,

I want to know if there are a function to calculate the Continuous Wavelet Transform and making an scalogram of any signal.

I have a signal with 262144 bins and sampled to 200.000.000 (200Mbs). It's a huge signal and then very hard to compute the cwt and represent to it (I think...).

If you have a script to compute the cwt and plot the scalogram... Welcome back ! ;-)

Regards and I waiting for your response.

Atte,

Alex

I realize your post is so old now, but still would like to share my experience here. SciPy has CWT but it appears to be totally unusable. I found CWT from http://mlpy.sourceforge.net/docs/3.5/wavelet.html#continuous-wavelet-transform the most flexible and straightforward. Later on I stumbled upon https://github.com/Dapid/fast-pycwt and https://github.com/aaren/wavelets but haven't yet tested them.

Which implementation did you eventually use?
