Sorting Data into managable sections for analysis

Hey,
If I have the following set of data for example:
10 10 10 5 5 5 0 0 0 -5 -5 -5 -10 -10 -10 -5 -5 -5 0 0 0 5 5 5 10 10 10
and so on (the cycle repeats), I want to be able to analyze the cycles individually. For example, the I want to first analyze the first 10:-10 cycle, then do the same with the next 10:-10 cycle, and so on and so forth. Can someone tell me how I can do this?
I was thinking using the find function in order to specify my window range, but find will not allow me to include the zeros. Any suggestions to help me look in the right place would be much appreciated! (:

Still trying to clarify. If your vector was x = [1 2 1 2 1 2 1 2], you would want to return y = [1 2]? And if x = [6 5 4 1 6 5 4 1 6 5 4 1], you would want to return y = [6 5 4 1]? In other words, you want to detect a repeating pattern, and return one instance of that pattern?

You are absolutely right, but I want multiple vectors. In taking your example,
let us say data was represented in excel as (the numbers on the far left represent rows in column A):
Column A
1 1
2 2
3 1
4 2
5 1
6 2
7 1
8 2
I want to be able to detect the pattern and then return ALL instances of the pattern. So vector X would be:
X = [1 2] which represents the data in rows 1 and 2 in excel.
Vector Y would be:
Y = [1 2] which represents the data in rows 3 and 4 in excel. Etc etc.
