Error using movmax index

I need to find the number of periods since a stock price recorded an 14-day high. My proposed method was to use the following andpossibly subtract the index from the current row:
n = 14
[M,I] = movmax(high,[n-1 0],'omitnan');
However, I return - "error using movmax. Too many output arguments."
Can someone please assist in my methodology.

There is no syntax for movmax() in which it returns a second output. It does not return the indices of the local maxima.

wid = 5;
N = 50;
signal = randi([-9, 9], 1, N)
for K = 1 : N - wid + 1
[M(K), relI] = max(signal(K:K+wid-1));
I(K) = K + relI - 1;
end
M
I
