For older releases such as 2007a, the toolbox is based upon Maple, and is now available from Maplesoft. It is essentially some interface code that calls upon the full version of Maple, and as such requires a full Maple license, which costs about $1900 for a node-locked license. Newer releases (by 2008b for sure, 2008a I think was the first) use MuPad as the symbolic engine; for them, the Symbolic Toolbox is available from Mathworks; I do not know the cost.

You should check with the person responsible for maintaining your license. It's possible that this toolbox is available on your license but just isn't installed in the installation you're using. If this toolbox is not present on your license, you should probably have the license maintainer contact your sales representative or our general sales staff: http://www.mathworks.com/company/aboutus/contact_us/ or use the Store link in the upper-right corner of that page to add it to your license. -- Steve Lord slord(a)mathworks.com comp.soft-sys.matlab (CSSM) FAQ: http://matlabwiki.mathworks.com/MATLAB_FAQ To contact Technical Support use the Contact Us link on http://www.mathworks.com |
