MATLAB: What is the difference between the complex morlet waveform and the morlet wavelet transformation (cwt)

complex morletwavelet

Hi, thats my question: What is the difference between the complex morlet waveform and the morlet wavelet transformation (cwt)? Any ideas? Thanks, Peter

Complex-valued wavelets are useful in cases where you want to analyze phase as well as magnitude.
Additionally, complex-valued wavelets that are analytic (have their frequency support on only 1/2 the real line) offer other advantages in the analysis of modulated signals (just for example). Note that the 'morl' option with cwtft.m is the analytic Morlet wavelet.
