I implement symbolic calculations using 'maxima': .

The tool is able to read commands from stdin or from file, and its stdout can 
be redirected to file, or it can be made to write to files.

This all makes the answer pretty obvious, doesn't it ? I.e. one can from 
'octave' call 'maxima' using 'system'. Creating the needed 'maxima' script 
before that.

'maxima' can write out data in various kinds of syntax. And identifiers can be 
made to contain '[\, ']' - which is good for "C". But in any case simple search 
and replace can do the trick, i.e. in 'maxima' one can use something like 
some_matrix__OB__3__comma__4__CB__, and then do the replacements: __OB__ -> (, 
__comma__ -> , , __CB__ -> ).
