Using movmean to calculate mean of first and last element in array

6 views (last 30 days)
I have an array [1 5 8 10] and using movmean with window length [0 1] this gives me [3 6.5 9 10]. Is there a way in which I can use movmean to calculate the mean of 10 and 1 as well and add that in the fourth position of the array?

What about this?
a = [1 5 8 10];
ma = movmean([a, a(1)], [0 1], 'Endpoints', 'discard')
ma = 1×4
3.0000 6.5000 9.0000 5.5000

Just set dim to 2:
a = [1 5 8 10;3 4 5 12];
ma = movmean([a, a(:, 1)], [0 1], 2, 'Endpoints', 'discard')
ma = 2×4
3.0000 6.5000 9.0000 5.5000 3.5000 4.5000 8.5000 7.5000
