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?

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