(3.2' (modified 3.2)): a(t) = 0.5 * acc * sin(PI * t /dtmax - PI/2) - 0.5 * acc (3.4) dtmax = 0.5 * PI * acc / jmax I think I made mistakes for integrating 3.2' for vel(t) and pos(t).
I would like to learn how to use octave to integrate 3.2'. I'm newbie to octave. Any guide would be appreciate. -Yishin ------------------------------------------------------------------------------ Live Security Virtual Conference Exclusive live event will cover all the ways today's security and threat landscape has changed and how IT managers can respond.
