hi everyone, I was wondering how to sum my calculation inside loop. here is a simple code:

 for i=1:5
   a = price1 * i;
   b =sum(a)
    %

so how to sum a, when i type like this it gives result (b=a) for every times. It does not add(sum) all of the results

I figured out

% %

 a=0;
 for i =1:5
a = a + (price1 * i)
    % code
  end

b = 0;
for k = 1:5
  a = price1 * k;
  b = b + sum(a);   % Or b = b + a?
end
