MatLab Functions:
EntropyHub functions fall into 5 categories:
- Base
functions for estimating the entropy of a single univariate time series.
- Cross
functions for estimating the entropy between two univariate time series.
- Bidimensional
functions for estimating the entropy of a two-dimensional univariate matrix.
- Multiscale
functions for estimating the multiscale entropy of a single univariate time series using any of the Base entropy functions.
- Multiscale Cross
functions for estimating the multiscale entropy between two univariate time series using any of the Cross-entropy functions.
When new entropies are published in the scientific literature, efforts will be made to incorporate them in future releases.
