The Mirror C++ reflection library provides both compile-time and run-time meta-data describing common C++ program constructs like namespaces, types, enumerations, classes, their base classes and member variables, constructors, etc. and provides generic interfaces for their introspection. It also provides several high-level utilities based on the reflected meta-data like a factory generator, which generates, at compile-time, implementations of object factories which can create instances of arbitrary 'reflectable' type.
omnisode.rb, preodein.rb, and preindent.rb are a set of Ruby programs to generate a program to use long Taylor series to solve systems of ordinary differential equations. It generates code to solve the equations in either C, C++, Ruby, Maple, or Maxima. Using the Taylor series, estimates are made of the location of poles.
