they're two symbolic toolboxes available for scilab :

- the OVLD/SYM toolbox by J-F Magni
- the overload/scimax toolbox by C. Denizet
http://forge.scilab.org/index.php/p/scimax/

both toolbox use maxima to do symbolic calculations so you need first to 
install maxima (http://maxima.sourceforge.net/). there differences lie 
in the maxima/scilab communication

- for the OVLD/SYM toolbox by J-F Magni communication between maxima an 
scilab   was based on a socket and a perl script so it's a little bit 
slow (and requires that perl be installed) but it works on both windows 
and unix
- after the death of J-F Magni (2008?) C. Denizet write a similar 
toolbox (overload/scimax) where the communication between scilab and 
maxima was greatly improved but it works only on unix system (because 
communication use "fork"?).

Since J-F Magni death 3 year ago is toolbox is not maintained any more 
but it still works fine with scilab 5.x after some modifications (see 
http://www.equalis.com/forums/posts.asp?topic=258177&) the biggest 
problem is to retrieve OVLD/SYM source code since J-F Magni web page has 
disappear of the onera website ((http://www.cert.fr/). So you should try 
overload/scimax ...
