Finally, I release my first version of MExpr library!
A C++ Library that parses mathematical expressions. The library is made using bison and flex. Evaluation on the AST Tree browsing it recursively. Ability to compile the expression in a bytecode that uses a stack to be evaluated. Support for variables, for implicit multiplications like -3xy^2, for functions and for overloaded functions. Furthermore, there is a set of standard functions taken from math.h.
