I have a signal (32Hz sampling rate) and I have to evaluate it's frequency using Wavelet transform. The most interesting frequencies are from 0.005 - 2 HZ and I want to evaluate their power...
I would like to plot a - 3D plot (frequency / time / power) - 2D plot
Please give me instructions to do that. Thank you!

Hi Marko, Do you have access to R2015b or later? If so, take a look at this example:

Hi one more time
in this article: They say they choose scales between 0.5 and 200. The scale was discretized with sigma=1.05. scale 0.5 corresponds 2Hz and scale 200 corresponds 0.005Hz...according to scal2frq function, this frequencies are different in my case... How they get frequencies between 0.005Hz - 2 Hz?
