Are you asking for a specific command, or how to go about creating a program that will get you that result from a series of calculations replicating what you yourself would do "by inspection"?
It should be straightforward how to do the latter. I don't think I can help with the former.

The largest value of magic(7) is 49
M = magic(7);
[ val, ix ] = sort(M(:),'descend');
[rr,cc] = ind2sub( [7,7],ix(1:10) );
>> [rr(1),cc(1)]
ans =
7 4
>> M(rr(1),cc(1))
ans =
49
>> M(rr(10),cc(10))
ans =
40
is one way to find the 10 largest values
