how to reach amount of entropy of image in between the range [0,1] in matlab?

Usually the amount of entropy is between the range [0,1]. but after run

 E = entropy(I)

E is a scalar value representing the entropy of grayscale image I that E>1.i want E between [0,1]. please guide me or suggest an another function.

You can scale the output by the maximum entropy for this image.

 H = entropy(I);
 N = numel(I);
 maxH = entropy([1:N]/N);
 Hscaled = H/maxH;
