Hi! This is my first post on this forum and I hope someone will be able to help me. I have an accelerometer (builtin - iPhone) and I'm trying to filter the acceleration from the accelerometer. I've tried low and high pass filters but I also need a kalman filter. What a need is a complete model - set of matricies (transition, state, control matrix and other) which I could use in my program. I'm trying to create a speedometer for the iPhone (a scientific project). For now I need a one-dimensional (beacause I use only one acceleration along the "Y" axis) filter, later I'd like to upgrade that to a three-dimensional. Thanks in advance for any assistance You may provide.
