Problem 3108. Don't Try, give up and return NaN.

This is another version of problem 3107.

The goal is to return values of an array A given index N, but return NaN for incorrect index.

Example:

    >> A = 1:5;
    >> N = [-1 2 6];
    >> values = giveup(A, N)
    values =
       NaN     2     NaN
