Hi, Whenever I try to run this code:

for i=1:3
    H=hilb(n);
    x = ones (n(i),1);
    b=H*x;
    y=mldivide(H,b);
    disp(y);
end

I get the following error: "Subscripted assignment dimension mismatch". I'm not really sure why since as far as I can see and when I set debug stops b is 5x1 and H is 5x5 on the first loop. Any help would be appreciated, Kiran

What is n? A vector? Maybe you need:

H = hilb(n(i));
