Santino, Can you please explain in more detail what you mean by the "wavelet covariance transform" of a function. Are you sure you don't mean wavelet coherence between two functions? Or do you mean, given some data, how do I compute the wavelet autocorrelation (autocovariance) for that dat...

原文「Cross-brain synchrony (coherence) was evaluated using wavelet analysis in the MATLAB 2018A Wavelet Toolbox. The wavelet kernel was a complex Gaussian provided by MATLAB. The number of octaves was four, and the range of frequencies was 0.4–0.025 Hz. The number of voices per octave was...
the continuous wavelet transform (CWT), scalograms, and wavelet coherence. It also provides algorithms and visualizations for discrete wavelet analysis, including decimated, nondecimated, dual-tree, and wavelet packet transforms. In addition, you can extend the toolbox algorithms with custom wavelets...
The MATLAB function “wcoherence” is used to compute the wavelet coherency between two signals in this study. One can find the wavelet coherency of analytical signals in the documentation of the MATLAB function, which reveals the ability of wavelet coherency to analyze the scale and phase relatio...
