%% Return Only Full-Window Variances % Compute the three-point centered moving variance of a row vector, but discard % any calculation that uses fewer than three points from the output. In % other words, return only the variances computed from a full three-element % window, discarding endpoint calculations. A = [4 8 6 -1 -2 -3 -1 3 4 5]; M = movvar(A,3,'Endpoints','discard')
