euclideanDistance.m

% euclideanDistance function calculates the eucledian distance between individuals.
% Input Parameters  : [r,c] specifies particular individual.
% Output Parameters : distance matrix specifies calculated distance between
%                     individual and its neighbors.

function [distance] = euclideanDistance(r,c,row_index1,row_index2,column_index1,column_index2)           
         x_index = 1 ; % x_index for distance matrix
         y_index = 1 ; % y_index for distance matrix
