I have an array of values I get from a sensor and the values undergo damped oscillated after the first few seconds. I want to find the point across which it oscillates. Can someone help me out?

It might be enough to use mean on the second half of your vector. Sometimes a simple solution will already do the trick.
The alternative would be to fit a function to your data, or to do a Fourier transform and keep only the low frequencies.

A sample plot would help, especially with a note about significant differences that might be detected before the damped oscillations.

The oscillations you can see from about 3 secons till 12 seconds is what I am talking about. Since it is not about 0, I want to find the new point.
