Detailed Description

A wrapper class for a VectorFunction instance that allows its evaluate(...) method to be accessed using a function prototype of the form int (*f)(double*t, double*y, double*yp).

This function prototype is that required by the f2c translation of rkf45, a Runge-Kutta-Fehlberg 45 implementation.

Since the VectorFunction class has no explicit t dependence, the t argument is ignored in the evaluation process.

yp is determined from y using the evaluate member function of the associated VectorFunction.

Typical use:

1. Set the dimension
2. Set the associated VectorFunction (or class derived from VectorFunction)
3. Pass the function fortranODEfunction::f to the external routine.

Samples of setting the dimension and setting the function are

     fortranODEfunction::setDimension(2);
     fortranODEfunction::setFunction(&F);
   

The function fortranODEfunction::f has type int (*f)(double*, double*, double*) and so

 fortranODEfunction::f 

may be passed to function whose argument is a function pointer of that type.

Fortran routines require that the member function of a class passed into it be a static member function, hence there can only one instance of this class in use in a specific program.
