Motion Profiling VI

What about initial and final acceleration?

Right now the profiles it produces are acceleration limited, not jerk limited. So (as I understand it) initial and final accelerations are not needed - they are always 0 in this model. My next version will be jerk-limited so it will include max jerk and initial and final accelerations. You have more experience with this stuff than I do, so let me know if I'm mistaken with this.

Have you ever ridden in a car with a student driver who, when approaching a stop sign, keeps their foot pressed on the brake pedal with constant force all the way until the car jerks to a stop?

That's what you get if your acceleration (deceleration) is not tapered to zero as you approach the destination.
