Problem 1927. Find nth maximum
Find nth maximum in a vector of integer numbers. Return NaN if no such number exists.
x = [2 6 4 9 -10 3 1 5 -10];
So
- n_max(x,3) would find 3rd maximum value in x which is 5
- n_max(x,8) would find 8th maximum value in x which is -10
- n_max(x,9) would find 9th maximum value in x which is -10
- n_max(x,12) does not exist so return NaN

I think the test cases are not correct. Can you check this?

The test cases expect isequal(NaN,NaN) to return true. This is wrong.

I went ahead and made the test suite change that José suggested above.
