marginals and energy of the scalogram to match the signal

Hi there: I have been looking for some matlab code to compute the time and frequency marginals in the wavelet scalogram.
Moreover I was trying to to verify the so-called total energy condition of the scalogram, basically the energy of the scalogram should match the energy of the signal.
I have done a double integral of the scalogram and the result doesn´t match the energy of the signal, so I should be doing something wrong since the result should be wavelet dependent, and we should take that in account when calculating the energy of the signal.
integral(integral(P(f,t))= sum(norm(s(t)).^2)
P(f,t)= scalogram and s(t) signal
Time marginal: integral(P(f,t)df=|s(t)|.^2 Frequency marginal integral(P(f,t)dt=|S(w)|.^2 Any ideas? Thanks
