Hi

I am trying to give an angular motion to a revolute joint in simscape through a step input where the motion starts from an initial value of 0 deg to final value of 45 deg in 5 seconds. I need a cubic polynomial curve from that input. The curve should be as shown in the attachment. i dont know how to modify it. please help.

Thanks in advance.
