WebI have an intermediate understanding of wavelet transforms and their application but I'm new to the matlab toolbox. I'm able to use the cwtft function but I'm having trouble with the cwt function. If I have a time series xn, that has a sample frequency fs I can generate a pcolor plot of time vs. frequency vs. wavelet power spectra (WPS=2*abs ... WebJun 1, 2016 · In that code sample, I am using scal2freq to estimate those scales (knowing that it is involutory, ie that scal2frq(scal2frq(x,'morl',dt),'morl',dt) == x up to numerical precision for all x, dt), but then I would expect that the frequency estimates returned by cwtft would be similar. As you can see, they are not.
