(6.36) is (almost) a wavelet, that is, a zero-mean function, the central frequency ωc must be greater than 5. The term 1/π4 ensures that the wavelet has unit energy. The Fourier transform of the complex Morlet wavelet is given by: (6.37)Ψˆω=2π4e−ω−ωc22 and hence ...

When using cwt on a simple sinusoid, cmor gives a weird result : While non complex morlet or whatever other complex ones such as cgaus gives somethings that seems more correct :

It is demonstrated that the usage of the Morlet wavelet as the analyzing function can be consid- ered as a generalization of Andronov's decomposition over limit cycles and, supplied with a special smooth- ing procedure, allows for building bifurcation diagrams highlighting the specificity of changes...
We also have added layers to do the 2-D DTCWT based scatternet. This is similar to the Morlet based scatternet inKymatIO, but is roughly 10 times faster. If you use this repo, please cite my PhD thesis, chapter 3:https://doi.org/10.17863/CAM.53748. ...
