Quaternion
Quaternion Toolbox for Matlab. Matlab® is a proprietary software system for calculating with matrices of real and complex numbers, developed and sold by The MathWorks. 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. For an introduction to octonions, refer to the Wikipedia article: Octonions. 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). From version 2 of the toolbox, octonions are also supported (but not to the same extent, or with the same level of maturity as the quaternions).
