Calculate column means ignoring NaN values in a matrix

[member 428835]

Hi PF!

Given a matrix A = [1 2; nan 3; 3 4], how can I calculate the mean so that the resulting matrix averages the columns but ignores the nan values as non-entries, so that the mean of matrix A outputs [2,3]?

Thanks so much!

>> A = [1 2; nan 3; 3 4];
>> avg = mean(A, 1, 'omitnan')

avg =

     2     3
