Hello Experts,
Consider I have to sum from i=1 to 2^(n-1) (n is given) values of some function f(i).
How can I do it like series in math sum from i=1 to 2^(n-1) of f(i)...
Thanks a lot in advance.

n=given;
i=1:2^(n-1); %gives you array of integers from 1,2,...2^(n-1)
% let's say your function is f=2i;
f=2*i;
yoursum=sum(f);

Function f is transferred as anonymous one to my function.
What should I change?

n=given;
fsum = 0;
for i=1:2^(n-1)
fsum = fsum + f(i);
end
