speed up max function

How to speed up max function? The following line [a,b] = max(c(1:24,1,2,3)) takes 2685.49s for calling 541390285 times. Is there any way to speed up?

   c=randi(100,[24,3,3,3]); 
   for i=1:1000000
   [a,b] = max(c(1:24,1,2,3));
   end

A significant fraction is undoubtedly the addressing of the 4D array; the same fragment but

   d=c(1:24,1,2,3);
   for i=1:1000000
     [a,b] = max(d);
   end

cut the time by almost 50%. Whether the real application allows that simplification is unknown, but the concept of reducing the data structure overhead is key one.
