I geht this error message when I try to derive my acceleration of the car. I think there is a size problem, but I don't know how to solve it. The data is measured from a car.
meas.jerk.data = diff(meas.acc.data); meas.jerk.time = meas.acc.time;
I think I have to do something like this but I really don't know.
size(diff(meas.acc.data)) = size(meas.acc.data)
