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.
