问题 I'm trying to reconstruct the original time series from a Morlet's wavelet transform. I'm working in R, package Rwave, function cwt. The result of this function is a matrix of n*m (n=period, m=time) containing complex values. To reconstruct the signal I used the formula (11) in Torrence & Compo classic text, but the result has nothing to do with the original signal. I'm specially concerned with the division between the real part of the wavelet transform and the scale, this step distorts
