Assignment has more non-singleton rhs dimensions than non-singleton subscripts

Hi, Im getting error in (line 16) x(i,i) = xl+(xu - xl).*rand(2,1);

Im new in matlab, and I cant solve that error in rand

N = 50;
D = 2;
xl = [-5 ; -5];
xu = [5 ; 5];
aptitud = zeros(1,N);
x = zeros(2,N);
for i=1:N
    x(i,i) = xl+(xu - xl).*rand(2,1);
end

Your ‘x(i,i)’ references a single scalar value. To assign the result to a column of ‘x’, do this:

x(:,i) = xl+(xu - xl).*rand(2,1);

That worked when I tested it.
