Summing values in a loop

Hi, how would I add values in a loop after iteration. eg. say values that came out were 1,2,3,4,5. I would want an array of 1,3,6,10,15. So 3rd number is first 3 added together and 5th is the first 5 etc. Thank you.

 iiTerm = zeros(10,1)
 for ii = 1:10
   iiTerm(ii) = (((-1).^(ii-1)).*(((pi/4).^(2.*(ii-1))))./(factorial(2.*(ii-1))));
 end

You mean

for ii = 1:10
   iiTerm(ii) = (((-1).^(ii-1)).*(((pi/4).^(2.*(ii-1))))./(factorial(2.*(ii-1))));
end
iiSum = cumsum(iiTerm);

?

Best wishes

Torsten.
