Greetings everyone, I'm trying to create a function called proms that returns mm, which is the average of the squares of the first nn positive integers, where nn is a positive integer and is the only input argument. For example sum(). My code is this:
Thank you dear friends!

Don't post a picture of your code. Paste in the code itself. It is just text! Then someone else can paste that code into MATLAB to help you. While this is not a lot of code, it still slows down someone who might help you. Do you really want to make it even slightly more difficult to get help?

Ok thank you dear friend
function mm=proms(nn)
nn=(x+1).^2
sum(nn)/n
end

Ran in:
Here's one basic way:
proms(5)
ans = 11
proms(11)
ans = 46
function mm = proms(nn)
% MM = PROMS(NN)
% calculate the mean square of the positive integers
% less than and equal to NN
mm = mean((1:nn).^2);
end
... or for further simplification, see this thread:
