hi , I wanted to implement Morlet based CWT function
Morlet wavlet is
my aim is to find the CWT coefficients a,b (scaling, shifting parameters) I have a recorded audio signal has 81410x1 double & sampling rate is 44100
x=audioread('rec2.wav'); a0 = 2^(1/32); scales = a0.^(0.5*32:1*32); % scaling has to be 1.65 to 2 , Is this right way to scaling ? [cfs,sc,frequencies] = cwt(x,scales,'cmor1-1.5',1,'scal');
when i run this code i was getting cfs [13x81410] complex double matrix
So this cfs matrix represents a & b from the 1st equn ? and trying to plot the cfs matrix , how to do that? and Later i want to do squaring of a&b coeff and plot it ?
