scripts default iconEntropy (Scripts) Publisher's description

Entropy: Returns entropy (in bits) of each column of 'X'

Entropy: Returns entropy (in bits) of each column of 'X'

by Will Dwinnell

H = Entropy(X)

H = row vector of calculated entropies (in bits)
X = data to be analyzed

Note 1: Each distinct value in X is considered a unique value.

Note 2: Estimated entropy values are slightly less than true,
due to finite sample size.


X = ceil(repmat([2 4 8 16],[1e3,1]) .* rand(1e3,4));

System Requirements:

MATLAB 6.0 (R12)
Program Release Status: New Release
Program Install Support: Install and Uninstall
