Why my user-defined matlab function returns NaN?

I wrote a matlab function but when the input argument vector has only one element, it returns NaN. I checked my code and I think everything is OK.

The W argument is a n x 1 vector or a 1 x n vector of weights that sum 1. However, when W = 1, the function returns NaN.

I think it is a bug of my Matlab version (2023b for Mac Intel).

Thanks in advance for your help.

W = 1;
orn = Orness(W)

orn = 1

function orn = Orness(W)
    nW = numel(W);
    if nW >= 2
        orn = zeros(nW,1);
        for j = 1:nW
            orn(j) = ((nW-j)/(nW-1))*W(j);
        end
        orn = sum(orn);
    elseif nW == 1
        orn = 1;
    end
end

I cannot reproduce the behaviour you describe (see above).

Hi, thank you for the command. My path have two Orness functions (one very old). The script is using that function instead of the new one.

So I made the mistake. I renamed the new function and the problem is fixed.

This solved my issue.
