how to evaluate user defined functions?

[Viktor Winschel]

Hi,

I need to input user defined functions,
lets say f(x,y)=log(x)+exp(y)
from a file at runtime and then evaluate them many times.

Since most of the runtime is spend on evaluating
the function I need a fast way to do it.

thanks

Google for "C++ interpreter". And look in the news archives as well.

Don't we all?...
