Hello! Please tell me if there is a way to build a CWT (or to be more precise, a CWT analog for a discrete signal) of a signal in Sage. The task is to obtain a time evolution of the spectrum (more or less) for the recorded signal in the form of time series. I've found the good examples of what I mean here.

Thanks.
