Hello, I have calculated Vehicle Speed which has steps in it. The steps were removed using the smoothdata() function. Later I used diff(Vehicle_Speed) / diff (time) to calculate acceleration which is very noisy. Using smoothing factor of 0.99 and different methods doesn't show any change but a smoothing factor of 1 gives a straight line. Is there any other way I can get smooth acceleration. As my further calculations are hindered due to acceleration data.
For information, I am working on a longitudinal model of a vehicle to calculate tractive force.

can you share your code and data ?

For best results (assuming equal-sized vectors), use:
gradient(Vehicle_Speed) ./ gradient(time)
instead.
