Detailed Description

This is a Constraint that uses a Function to prescribe the behavior of a single generalized coordinate as a function of time.

You provide a Function which takes the current time as its argument and returns the required value of the generalized coordinate. It also must support derivatives up to second order.

Constructor & Destructor Documentation

SimTK::Constraint::PrescribedMotion::PrescribedMotion	(	SimbodyMatterSubsystem &	matter,
		const Function *	function,
		MobilizedBodyIndex	coordBody,
		MobilizerQIndex	coordIndex
	)

Create a PrescribedMotion constraint.

You specify a Function that takes time as its single argument, and returns the required value for the constrained coordinate.

Parameters:

matter	The matter subsystem to which this constraint will be added.
function	The Function which specifies the value of the constrained coordinate. The constraint takes over ownership of this object, and automatically deletes it when the constraint is deleted.
coordBody	The MobilizedBody corresponding to the generalized coordinate which will be constrained.
coordIndex	The index of the generalized coordinate which will be constrained.
