Hi I need to find maximum and second maximum number in a vector. Can you please help?
For max, its max(X), but for second max I am unable to figure out.
Your help is appreciated

a = max(X);
Y = X(X ~= a);
b = max(Y);

There are apparently efficient linear-time routines to find the N largest or N smallest numbers in a list, and supposedly they do not need to do a mini-sort of N elements to find the proper place in the list for each new value being tested. I have not yet been able to understand the logic in the paper that describes the internal comparison scheme.
