aruduino uno coding about acceleration and deceleration to stepper motor.

I need to control stepper motor with arduino uno. I want to control 2 motors at the same time. firstly i want to rotate first motor only 30 degrees with acceleration (for example. kind of 0->1 -> 2> 3> 4>- ~~~ >100, and it should take 1second reaching from start to the end. and them should rotate back from the end to the start point with deceleration kind of 50 -~~ 4>3>2>1>0 ) secondly i want to rotate another motor only 45 degrees with acceleration (for example. kind of 0->1 -> 2> 3> 4>- ~~~ >100, and it should take 1second reaching from start to the end. and them should rotate back from the end to the start point with deceleration kind of 50 -~~ 4>3>2>1>0 ) and then two motors should wait 3 seconds and then two motors should rotate continously as I wrote above. and plz let me know where can I change the code for aujusting about degrees and waiting timing. i am very urgent so plz make the code in 1 or 2 hours. thank you
