func_FE_ShannEn

This function calculates Shannon Entropy

% This function calculates Shannon Entropy based on the following algorithm

%------------------------------------------------------------------------------------

% - The number of n intervals of the signal is selected.

% - The width of each interval is calculated from the formula (xmax-xmin)/n.

% - The number of points of the signal that are placed in each interval is counted: Ni i = 1: n

% - Probability pi = Ni / N is calculated.

% - Shannon entropy is calculated using the formula H=-sum(pi.log2(pi)) i=1->n.

% Input parameters:

% - signal: Input signal must be a vector with dimension N

% - n: number of devision %

%

% Output:

% - ShannEn: Shannon entropy value
