MATLAB: Sum inside a for loob

for loopsumsummationtotalwhile loop

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

Best Answer

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