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
