that is the problem: you use symbols with names "0" and "1" !
Wouldn't that eliminate functional dependence on the variables represented by f1 & f2, making the return value a function of "0" and "1". The end user could handle this by manually simplifying the output, but that wouldn't be optimal.
I don't know what you mean, but the "0","1",etc. are just names for the output and are _completely_ irrelevant for any algebraic operation. If you want to match patterns then you have to use the C++ variable name of the symbols you give to r_sum. Regards, Jens
