how can i analyze a signal with three coordinates

Asked by Lisa Justin on 17 Jul 2012

i have a signal from an accelerometer with 3 coordinates x,y, z. how do i analyze this signal so i have all three cordinates? Do you think taking an average of all three is right? Or should i just sum all three cordinates? or treat them uniquely for each direction

Accepted answer

It depends on what you want to do. What do you want to do? You have the acceleration vector. Do you want the acceleration magnitude (like the Pythagorean theorem would give you)? Or do you want something else? If you had the magnitude, what would you do with than information?

I found this routine in the File Exchange:

There may be others.
