MATLAB: How to compare two rows of an array withot for loop

Question

Hi! I want to compare two rows of an array. I want to do this:

I hace a = [1 NaN 2 NaN;[2 NaN NaN 3];

I want to create another array without using for loop iteration and obtain the next array

–> If both have a value I want to obtain the mean value of them.

–> if one of them have NaN I want to obtain the number

–> If both have NaN I want to delete it

I want to obtain this:

c = [1,NaN,2,3]

Answer 1

Try this

a = [1 NaN 2 NaN];
b = [2 NaN NaN 3];
c = nanmean([a; b])

Result:

c =
    1.5000       NaN    2.0000    3.0000
