I use the entropy function given belwo for my data, but Matlab gives me an error.
e=entropy(x,'shannon')
Matlab gives me this error:
Error using entropy>ParseInputs (line 58)
Too many input arguments.
Error in entropy (line 38)
I = ParseInputs(varargin{:});

The entropy function only permits a single parameter.
You are probably thinking of the wentropy function, which does permit 'shannon' as a second parameter.

Dear Walter Roberson my code became now like this:
clear all
clc
load 2sn0_sorted;
fitness2sn0=one;
fitness2sn0=sort(fitness2sn0,'descend');
entropy1=wentropy(fitness2sn0,'shannon')
but it gives me a -ve value. Is it possible?
