Asked by Ms. Mat on 17 Jan 2013

A = [1 2 NaN; 4 NaN 6; 7 8 9]

A =

1 2 NaN 4 NaN 6 7 8 9

mn = nanmean(A,2)

mn =

1.5000 5.0000 8.0000

I would like to subtract each element by its corresponding row average as shown below(i.e find absolute deviations from mean),

1-1.5 2-1.5 NaN 4-5 NaN 6-5 7-8 8-8 9-8

Note the below array has no negative values as I am trying to find modulus of deviations.

0.5 0.5 NaN 1 NaN 1 1 0 1

Then sum up each row and divide by no. of elements.

(-0.5+0.5)/2 (-1 + 1)/2 (-1 + 0 + 1)/3

How can I achieve this result vector using arrayfun or by any other method ?

I am trying to find teh absolute deviation of each element in the array. i.e std.dev without the sq
