Hi!
I'm new in the forum, I have the following problem:
I'm working with a Phidget (0/0/3) sensor, I’m obtaining the data (acceleration in x, y, z) trough Mat lab, currently I’m plotting a vector where the position sensor is pointing, also an Cartesian coordinate system right in the middle of the plot.
My problem is that I want to stick the axis z direction to the movement of the sensor (position vector)
I hope I explain myself; I’m attaching the code and some images.
Thanks in advance
