Release History:
- Release date: 8 June 2012
- This current version of the software package contains MatLab programs for performing:

   - the partial wavelet coherence and multiple wavelet coherence
   - the wavelet power spectra and cross wavelet spectra modified based on the programs provided by Aslak Grinsted
     ( to correct the bias towards low-frequency oscillations.
