how to double integrate highly nonlinear numerical dataset

Dear all,
I need to find displacement data from the available acceleration dataset. All dataset is numerical and highly nonlinear.
I was wondering if there any efficient methods with the least error (e.g., trapezoid method may generate too errorneous answers.).
AND more importantly, are there any features in the signal processing and communucation app in matlab that facilitates such a signal processing to cinvert the acc. data into disp. data?
Thanks!

hello @Alireza Babaei
most of the issue is to handle properly the DC signal (in your acceleration signal what is "real" and what is offset error or drift , and how to avoid integrating them). without having an idea of what the result should be (in others terms, a tool that helps you calibrate your post processing) it's almost mission impossible to get this right.
