%% Moving Average of Vector with NaN Elements
% Compute the three-point centered moving average of a row vector containing two NaN elements.

A = [4 8 NaN -1 -2 -3 NaN 3 4 5];
M = movmean(A,3)

%
% Recalculate the average, but omit the NaN values. When movmean discards NaN elements, it takes the average over the remaining elements in the window.

M = movmean(A,3,'omitnan')
