Description: Quaternions are hypercomplex numbers (that is generalizations of the complex numbers to higher dimensions than two). For an introduction, refer to the Wikipedia article on Quaternions.
Quaternion toolbox for Matlab® extends Matlab® to allow calculation with matrices of quaternions in almost the same way that one calculates with matrices of complex numbers. This is achieved by defining a private type to represent quaternion matrices and overloadings of many standard Matlab® functions. The toolbox supports real and complex quaternions (that is quaternions with four real or complex components).-Quaternions are hypercomplex numbers (that is generalizations of the complex numbers to higher dimensions than two).

Description:
3D Space Coordinate Transformations
This folder contains 3 files (m-functions) :
- t2x.m Transformation Matrix to Generalized Position Vector.
- x2t.m Generalized Position Vector to Transformation Matrix.
- m2m.m Mass/Inertia Tensor transformation with coordinate change.
In the Generalized Position Vector the orientation can be expressed with:
- unit quaternion,
- Euler angles xyz (roll, pitch, and yaw),
- Euler angles zyz (rotation, precession, and mutation),
- unit vector and rotation angle,
- Denavitt-Hartemberg parameters.
Conversion between the above orientation systems can be easily achieved.
The three files work independently on each other, but since they work
on the same objects it is somewhat useful to keep them in the same folder. -
