MatLab Functions:

EntropyHub functions fall into 8 categories:

Base

functions for estimating the entropy of a single univariate time series.

Cross

functions for estimating the entropy between two univariate time series.

Multivariate

functions for estimating the entropy of a multivariate dataset.

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.

Multiscale Multivariate

functions for estimating the multivariate multiscale entropy of multivariate dataset using any of the Multivariate-entropy functions.

Other

Supplementary functions for various tasks related to EntropyHub and signal processing.


When new entropies are published in the scientific literature, efforts will be made to incorporate them in future releases.
