Definition at line 121 of file JointAccelerations.cpp.

◆ operator* [2/3]

JointVelocities operator*	(	const std::chrono::nanoseconds &	dt,
		const JointAccelerations &	accelerations
	)

friend

Integrate joint accelerations over a time period.

Parameters

dt	The time period used for integration
accelerations	The joint accelerations to be integrated

Returns: The resulting joint velocities after integration

Definition at line 138 of file JointAccelerations.cpp.

◆ operator* [3/3]

JointAccelerations operator*	(	double	lambda,
		const JointAccelerations &	accelerations
	)

friend

Scale joint accelerations by a scalar.

All joints in all the state variables are scaled by the same factor.

Parameters

lambda The scaling factor

Returns: The reference to the scaled joint state

Parameters

lambda	The scaling factor
accelerations	The joint accelerations to be scaled

Returns: The scaled joint accelerations

Definition at line 115 of file JointAccelerations.cpp.

◆ operator<<

std::ostream & operator<<	(	std::ostream &	os,
		const JointAccelerations &	accelerations
	)

friend

Overload the ostream operator for printing.

Parameters

os	The ostream to append the string representing the state
state	The state to print

Returns: The appended ostream
