K-Spectral Centroid: Cluster Time Series by Shape

Codes information

The K-Spectral Centroid algorithm clusters time series by their shape, and finds the most representative shape (the cluster centroid) for each cluster. We provide the simple version of the K-SC code for Matlab. For brevity, this version does not include the Haar-Wavelet based incremental implemention discussed in the paper.
