Version 3 adds symbolic computation with quaternions, provided that you have the Symbolic Math Toolbox (if you don't the numeric functionality will still work). Version 2 of the toolbox adds support for octonions. I'm not working on a student license either. Many Matlab operators and functions are overloaded to work for real quaternion and complexified quaternion matrices.

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 symbolic toolbox is based on the MAPLE kernel as an engine to handle symbolic mathematics. 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.
