??? Attempted to access degree(2); index out of bounds because numel(degree)=1.

hello

i have a matrice triangular of distance(n,n) between nodes and i want to calculate the degree (the degree is a vector(n)) :

• gca;

 if isfield(handles,'net')
    n=numel(handles.net(1,:));
    degree=0;
    for i = 1:n
    for j = i+1:n
        X1 = handles.net(2,i);
        Y1 = handles.net(3,i);
        X2 = handles.net(2,j);
        Y2 = handles.net(3,j);
        xSide = abs(X2-X1);
        ySide = abs(Y2-Y1);
        d = sqrt(xSide^2+ySide^2);% 
        if (d<=2*(handles.r) )
            degree(i)= degree(i)+1
        end

    end

    end
 end

and have this msg error :

??? Attempted to access degree(2); index out of bounds because numel(degree)=1.

          degree(i)= degree(i)+1

Change

degree=0;

to

degree = zeros(n,1);
