Hi All,
I am having a vibration signal obtained by an accelerometer. i want to perform continuous wavelet transforms (CWT) on this signal and i can do that by using "cwt" command. i also want to calculate the energy of the signal from the wavelet coefficients. how can i calculate the signal energy from wavelet coefficients.

you can do the cwt of the signal coeff = cwt(x)
where coeff are you continuous wavelet transform and x is your signal
For energy energy = sqrt(sum(abs(coeff).^2,2)); percentage = 100*energy/sum(energy); [maxpercent,maxScaleIDX] = max(percentage)
