Storing output from inner for loop after every itteration of outer for loop in nested for loops.

I want to be able to store the output from n=1 and n=2 into an array.

With my current code a(1) is retrived as 0.124( sum of cos(n=1*m=1) and cos(n=1*m=2)) which is correct, but a(2) is retrieved as -0.945 which is incorrect.

I want a(2) to be -1.069(sum of cos(n=2*m=1) and cos(n=2*m=2)). How can i ensure it runs through inner loop for n value stores it to array, runs for inner loop for next n value and again stores it to the array?

a=zeros(1,2);
sum=0;
for n=1:2;
    for m=1:2;
        sum = sum + cos(n*m);
    end
    a(n)=sum;
end

thank you.

a=zeros(1,2);
for n=1:2
    sum = 0.0;
    for m=1:2
        sum = sum + cos(n*m);
    end
    a(n)=sum;
end
a

a = 1×2

0.1242 -1.0698
