Hi, There is the symbolic package (part of the octave-forge packages, I'm CC'ing this to its mailing-list), see http://octave.sourceforge.net/symbolic/index.html which may do some of the stuff you want. It doesn't have simplify() though, only expand(), and it may be missing some others. If you are interested, contributions for any package are always welcomed. You should be able to install the package with 'pkg install -forge symbolic' (if you're using a version older than 3.4, you'll need to download the package manually from the octave-forge site).
