%% Moving Variance of Matrix % Compute the three-point centered moving variance for each row % of a matrix. The window starts on the first row, slides horizontally to % the end of the row, then moves to the second row, and so on. The % dimension argument is two, which slides the window across the columns of % |A|. Always specify the normalization factor when specifying the % dimension. A = [4 8 6; -1 -2 -3; -1 3 4]; M = movvar(A,3,0,2)
