Orientation, Position, and Coordinate Systems
Represent orientation and rotation using the quaternion
data type. Convert between quaternions and Euler
angles, rotation matrices, and rotation vectors using the euler
, rotmat
, and rotvec
functions.
To learn more about quaternion mathematics and how they are implemented in Sensor Fusion and Tracking Toolbox™, see Rotations, Orientation, and Quaternions. To learn more about conventions and coordinate systems in Sensor Fusion and Tracking Toolbox, see Orientation, Position, and Coordinate Convention.

- Rotations, Orientation, and Quaternions
This example reviews concepts in three-dimensional rotations and how quaternions are used to describe orientation and rotations.
- Lowpass Filter Orientation Using Quaternion SLERP
This example shows how to use spherical linear interpolation (SLERP) to create sequences of quaternions and lowpass filter noisy trajectories.
