if there are many equals numbers, what you want to do, take them all? in this case there will be more than 10 values.

Try this:

    M = magic(4);
    N = 10;
    [ b, ix ] = sort( M(:), 'descend' );
    [ rr, cc ] = ind2sub( size(M), ix(1:N) );
    for ii = 1 : N
       disp( M( rr(ii), cc(ii) ) )
    end

% try this

    a=[1 2 7  8  8  5   20  20 40 0 1 8 77 77 87 87 52 36 87 12 78]';
    c=flipud(unique(sort(a))),    
    result=c(1:10);         %top ten
    ind=find(a>=c(10))      %their indices
    resultat=flipud(sortrows([a(ind) ind],1))  
% because there equals number , there is more than 10 classed. if you want take only %10 include this code
   resultat1=resultat(1:10,:)
