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.
