Rodrigo, you could use
a = [1 2 3 4 5 6 7 8 9 10];
b = max(setxor(a,max(a)));

Another option (which also allows you to pick any nth largest number):
a = [1 2 3 4 5 6 7 8 9 10];
ua = unique(a); %will sort a and remove duplicate
b = ua(end-1); %for the 2nd largest
b = ua(end-n+1); %for the nth largest
