LinearVelocity — Extraction of linear velocity of point relative to observer [maple]

Reference: Appendix B in Multibody Mechanics and Visualization by Harry Dankowicz, published by Springer Verlag UK, 2004.

Calling Sequence

LinearVelocity(O,P)

Parameters

O: name of defined observer

P: name of defined point

Description

The function LinearVelocity returns the linear velocity of the point P relative to the observer O.

Remember to invoke DeclareStates prior to using LinearVelocity.
