Prerequisite

• FunctionWrapper class
• WrapperData class

Synopsis

This base class is provided to enable compile time selection of the appropriate function call through WrapperData.

Example

Float func(const Vector<Float>& x) { return x(0)*x(1); }        // x*y
// Convert C++ functions to Functionals
FunctionWrapper<Float> Func(func, 2);
