How to save output in array

Hi, I'm trying to create a loop that prints the output in an array and not sure how to save/print as I want.

num=5;

for k=1:num

a=k^2;

num=num+1;

end

output=[a(1), a(2), a(3), a(4), a(5)]

Like this?

num = 5;
for k = 1:num
    a(k) = k^2;
end 
disp(a)

     1     4     9    16    25
