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

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

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

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