WebbShannon's entropy index is a measure of the entropy, that applies to any numerical data, developed by Claude Shannon in the 1940s. It measures the frequencies of appearance … WebbAdd a comment. 8. You may be interested in the Von Neumann entropy of a matrix, which is defined as the sum of the entropies of the eigenvalues. Ie, for. A = P [ λ 1 λ 2 … λ n] P − 1. with positive λ i, the entropy is, H ( A) := − ∑ i λ i log λ i.
