MATLAB code to compute W1 and D indices

• Index W1 is L1 norm of the difference (or Wasserstein distance with exponent one) between CDFs of Power Spectral Density of two time series.
• Index D is the average difference between CDFs of Power Spectral Density of two time series.

W1 and D indices are introduced in the following paper:
