Yes all the same size and numeric. Matrix may changes in each loop

That's just a numeric vector. You said you have a matrix of arrays.

Ran in:
If all you need to work on is a numeric vector, then
W = [3 5 4 6 7 8 66 444 33 23 4];
Wmx = maxk(W,5) % R2017b or newer
Wmx = 1×5
444 66 33 23 8
Note that maxk() is relatively new. You can also do the same thing using sort()
% any version
Wmx = sort(W,'descend');
Wmx = Wmx(1:5)
Wmx = 1×5
444 66 33 23 8

use ind2sub() to convert the second output into a row and column number.
