A cross wavelet and wavelet coherence toolbox for MATLAB

A Matlab toolbox for performing cross wavelet and wavelet coherence analysis and is free for non-profit use.

Wavelet coherence between the winter Arctic Oscillation index and the sea ice extent in the Baltic.

Our paper describes the theory behind cross wavelet and wavelet coherence, starting from the basics of the Continuous Wavelet Transform: "Application of the cross wavelet transform and wavelet coherence to geophysical time series"
