Need help with a nested for loops

Hello everyone!I am trying to create a function that you can put a vector 'x' and a order 'N' to solve for the exp(x). It is close to being correct however i just can't seem to get it.

function [y] = nexp1(x,N)
U = length(x);
for k = 1:U
    asum = 0;
    for w = 1:length(x)
        new = (x(k).^w / factorial(w))
        asum = asum + new
    end
    y(k) = asum
end
end

Were you told to use nested FOR loops?

[Rob Mullins]

Yes must use nested

[Rob Mullins]

Well it tells to write a function using nested and then it says do it without nested.

Your

      for w = 1:length(x)

Should be

      for w = 0 : N

Awesome thanks! Can you explain on how to do it with only 1 for loop? I assume you would need to vectorize the inside FOR loop?

[Walter Roberson]

Yes you would vectorize the inside for loop.
