In the matlab (2018b) waveletAnalyzer GUI tool for a continuous wavelet 1-D analysis, there is a "Coloration Mode" drop down menu with the choices "by scale" or "all scales". According to here, the difference is:
"When you select by scale, the coloration is done separately for each scale. When you select all scales, all scales are used".
I want to export the wavelet coefficient matrix and reproduce the "by scales" plot outside the wavelet GUI tool. I found that I can reproduce the "all scales" plot simply with:
imagesc(my_VAR_1.coefs)
where my_VAR_1 is the exported wavelet variable from the GUI. But how can I reproduce the "by scales" plot? Is there a command for this?
As a followup question, does anyone know how to reproduce the "Local Maxima Lines" plot from the GUI? I tried the 'spy' function on the coefficient matrix but the results aren't as nice looking.
