MATLAB: Cell contents reference from a non-cell array object.

getting error

clear all;
clc;
%For ceating nodes(Sensor node)
num1 = input('Enter the no of nodes you want to consider in your WSN');
      radius = 30;
        for i= 1:num1
           X = rand(1,num1).*2;
           Y = rand(1,num1).*3;
        end
        X
        Y
        %Calculate Distance
        for i= 1:num1
            for j= i+1 : num1
                dist= sqrt((X{i}-X{j})^2+(Y{i}-Y{j})^2);
               % C=dist(i,j);
            end
        end
        disp(C)
I am getting error "Cell contents reference from a non-cell array object" for line dist= sqrt((X{i}-X{j})^2+(Y{i}-Y{j})^2);. Please tell me how to solve this problem.

Don't use the curly brackets. That tells Matlab its a cell when its not. It is an array. Write like this
dist= sqrt((X(i)-X(j))^2+(Y(i)-Y(j))^2);
