Need Code for Kinematics

I need the code for the following Kinematics equation

" Velocity

VB= AA + ( AB x r AB )

VC = VB + ( ω BC x r BC )

Accelaration

AB = AA +( ( AB X (ω AB x r AB )) + ( α AB x rAB)

AC = AB + ( ( BC X ( BC x r BC )) + ( α BC x r BC )

r AB = AB( sin θ i + cos θ j )

r BC = BC( sin α i + cos α j )

User need to input:

Distance: AB and BC

Angle: α and θ

k value = AB and α AB"

Need user ask to input

Hi Nandeeswaran,

It seems you are facing some difficulty in writing code for a kinematics equation. It would be better if you can point out in which step you are facing problem to get support from this forum. You can refer to the following MathWorks documentations for the key steps involved in the equation:
