Considering that John's last posting was over eight years ago (according to MATLAB Central) if you want to ask a question you should probably post it to the newsgroup rather than trying to email him. [Please do NOT email it to me directly either; post to the newsgroup so that everyone can read it and perhaps offer suggestions.]
That being said, ODE45 or CUMTRAPZ would be good first steps in integrating accelerometer data; use ODE45 if you have a function you've fit to the data that fits well/matches the theory behind your experiment, CUMTRAPZ if you have just the data itself.
