V2.0 Note:
For a list of all feature updates see the updates on www.EntropyHub.xyz.
The vast majority of EntropyHub functionality is compatible with R2016a and later. Only for some specific function calls will users require R2022a and later.

About
EntropyHub provides a comprehensive set of functions to estimate nonlinear dynamic and information theoretic entropy statistics from time series and image data.
EntropyHub has a simple and consistent syntax that allows the user to augment several parameters at the command line, enabling a range from basic to advanced entropy statistics to be implemented with ease.
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.
  • Multivariate Multiscale 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.
