Symbolic computation with octonions was added in version 3.1. (provided that the Symbolic Math Toolbox is installed). (but not to the same extent, or with the same level of maturity as the quaternions).įrom version 3 of the toolbox, symbolic computation with quaternions is also supported Toolbox supports real and complex quaternions (that is quaternions with four realįrom version 2 of the toolbox, octonions are also supported Quaternion matrices and overloadings of many standard Matlab® functions. This is achieved by defining a private type to represent Matrices of quaternions in almost the same way that one calculates with matrices Quaternion toolbox for Matlab® extends Matlab® to allow calculation with For an introduction, refer to the Wikipedia article onįor an introduction to octonions, refer to the Wikipedia article: Quaternions are hypercomplex numbers (that is generalizations of the complex numbers Matlab® is a proprietary software system for calculating with matrices of realĪnd complex numbers, developed and sold by The MathWorks. Which was first released on 3 August 2005. I'm not working on a student license either.Quaternion and octonion toolbox for Matlab Quaternion and octonion toolbox for Matlab® September 2015: QTFM release 2.2 marked the second decade of this open-source toolbox, I also realised that the documentation is always available when I take Help -> Product Help from the menu-bar, though it is not available in the function browser even after I try the sample code.ĮDIT-II > license('checkout','Symbolic_Toolbox') I'm not sure if this problem is just for this particular toolbox or not, but the other toolboxes I use at least seem to work fine. Some of them seem to blame it on MATLAB hashing the tollbox incorrectly, so I tried the rehash toolbox command as well, but had no luck. I found a few instances of other users facing similar problems on the Mathworks portal, but none of them seemed to provide any concrete solutions. However, the problem again arises when I close and reopen MATLAB. The code works fine and on trying the help command again, they seem to work fine as well. Moreover, when I try some simple code such as: > syms k x However, the toolbox seems to be installed when I try the ver or pathtool command. Type 'help help' for help command options, such as help for methods.

Use the Help browser Search tab to search the documentation, or When I try to access any function in the 'Symbolic Math Toolbox' in MATLAB, such as help ztrans or help laplace, I get the following kind of message ztrans not found. This problem may seem a bit weird please bear with me.
