what changes can be made in the code?

if input : mycumsum( [ 3 2 10 ] ) and i want is the vector sum of sum of 1st and second and so on eg [ 3 5 15 ]

function [out] = mycumsum (m)

add = 0;
for i = 1:length(m)
	for j = 1:length(m)+1
	a = i(m);
	%b = ;
	end
end
out = add;

MATLAB's cumsum will do this for you. Is this a programming excercise where you have to write your own code to do provide a cumulative sum?

[David Hill]

function out = mycumsum (m)
out = m(1);
for i = 2:length(m)
	out(i)=out(i-1)+m(i);
end
