I made a function, I hope help you

a = rand(4); %Example of 2D matrix
b = reshape(a,1,16);
cont = 0; var = zeros(1,length(b));
contM = 0;
for n=1:length(b)
   b(n);   
   for m = 1:length(b)
      if(b(n) > b(m)) 
          cont = cont+1;
      elseif(b(n)< b(m))
          contM = contM+1;
      end
      
      if(cont == 15)
          maximo = b(n);
      elseif (contM == 15)
          minimo = b(n);
      end
   end
       var(n) = cont;
       cont=0;
       contM=0;
end
suma = minimo+maximo;
