MATLAB: Iterating over an Array Using a “for” Loop.

loop

This is a very basic question and I would appreciate any help. I've written code to calculate the Fibonacci sequence using a “for” loop. I want to display the elements of the sequence whose indices are specified in the array “N”. The problem is that all displayed values are the same as the value associated with the first element of “N”. 
N=[10 100 1000];
first=1;
second=1;
for i=1:(N-2)   %The index has to have two terms removed because it starts with 1 and 1 already
        next=first+second;  %The current term in the series is a summation of the previous two terms
        first=second;   %Each term must by iterated upwards by an index of one
        second=next;    %The term that previously was second is now referred to as next
end
for i=1:length(N)
    disp([N(i) next])
end
Thanks

Donald, regarding your new "Answer", you can do it like this:
N=[10 100 1000];
for n = 1 : length(N)
  first=1;
  second=1;
  for k = 3 : N(n)   %The index has to have two terms removed because it starts with 1 and 1 already
    next = first+second;  %The current term in the series is a summation of the previous two terms
    first = second;   %Each term must by iterated upwards by an index of one
    second = next;    %The term that previously was second is now referred to as next
  end
  % Print to command window
  next
end
