How to solve a nested summation with recursive function?
显示 更早的评论
Hi,
I have a question related to solving a nested summation equation with a recursive function.
Suppose I have an equation of:
So, I tried to solve this problem by using a for loop to solve the summation equation and using a recursive function to expand the order of nested summation.
test(3,0)
function [sum] = test(a,b)
sum = 0;
for i=1:a-b
if a-b == 1
sum = 1;
else
sum = sum + (a-b) * test(a,b+i);
end
end
end
From the code I got
ans = 9
I appreciate any help, thanks.

I think your code is correct, and your calculation by hand is not.
