Coordinate Transformations and Trajectories

Quaternions, rotation matrices, transformations, trajectory generation

Robotics System Toolbox™ provides functions for transforming coordinates and units into the format required for your applications. To learn more about the different coordinate systems, see Coordinate Transformations in Robotics. You can also generate trajectories using polynomial equations, B-splines, rotation matrices, homogeneous transformations, or trapezoidal velocity profiles.
