DYNAMICAL

DYNAMICAL calculates the power spectrum of successive segments (of length 2**N) of a 1D data array subclass object (e.g. time series) and stacks the resulting spectra to form a dynamical power spectrum.

The normalisation of the power spectra is:

       power = (wave amplitude/2)**2 = F.T.of autocovariance.
The zero frequency power is omitted from the output array since it tends to dominate plots if included, and makes taking of logs difficult if zeroed.
