This MATLAB toolbox provides codes for computing practical measures of integrated information proposed in Oizumi et al., 2016, PLoS Comp Biol and Oizumi et al., 2016, PNAS and codes for efficiently searching the Minimum Information Partition (MIP) proposed in Hidaka & Oizumi, 2018, PLoS ONE and Kitazono et al., 2018, Entropy (Queyranne’s algorithm). Please see Readme.docx for more details.

The codes for Queyranne’s algorithm were written by Shohei Hidaka at JAIST (Japan Advanced Institute of Science and Technology).
