I recommend using Maxima: http://maxima.sourceforge.net/ . I outsource symbolic
transformations from Octave to Maxima.
If you want a GUI other than the TCL one which comes with Maxima, there is
WxMaxima: http://andrejv.github.com/wxmaxima/ /
You can also consider Fricas: http://fricas.sourceforge.net/ .
Both Maxima and Fricas are scriptable.
