RECURSION FUNCTION IN MATLAB USING ARRAY

i have an array n of size 100 (value of different index is different). after processing got an array of size half(50). i want to use this array as input to get an array of size 25.process will proceed until size of n be 1.for example

n=[1 2 3 4 5 6 7 8 9 ...100]
n1=[1 0 3 4 0 0 0 0 9...99 0]

i want n1 as input to generate array with 25 elements using only non negative elements

n=[1 2 3 4 5 6 7 8 9 ...100];
n1=n;
while numel(n1)>1
     % do
     % n1=

SANJOY, accepting an answer means your problem is solved. Now If you accepted the answer by accident, please make again, your question as clear as possible. You are asking about implementing something we don't know. I gave you above one way to do it in general, just adapt it to your problem. Is something not clear with that?
