MATLAB: How to average two arryas that have Nans

Question

I have two arrays:

A = [2 4 6 8]

B = [Nan 2 Nan 4]

I want to combine these two into one by averaging but ignoring the Nan so that the final result is:

C = [2 3 6 6]

How do I do this?

Answer 1

>> nanmean([A;B],1)
ans =
     2     3     6     6
