I developed a copy of libMesh::AnalyticFunction that uses boost::functions
as inputs. This allows for some additional flexibility when boost::bind is
used over the function pointer inputs of AnalyticFunction. Below is a
non-working code snippet of me using it to attach the Parameters class to
an initialization function (func2), similar to Example 9, but in this case
two variables are considered.
I have found this to be very useful, so I thought I would post the code in
case anyone is interested in using it. Note, I have placed the class in my
own namespace. I have successfully tested the use of this class for
attaching initialization and boundary conditions functions that are members
of a class.

--- CODE SNIPPET ---------------
void func2(DenseVector<Number>& output, const Point& p, const Real, const
Parameters& parameters){
/* return output(0) and output(1) */
}
// Generate the boost::function pointers
boost::function< void (DenseVector<Number>&, const Point&, const Real,
const Parameters&)> fptr_full;
boost::function< void (DenseVector<Number>&, const Point&, const Real)>
fptr_shrt;
// Link function to the full pointer
fptr_full = func2;
// Bind the parameters
fptr_shrt = boost::bind(fptr_full, _1, _2, _3, eq_sys.parameters);
// Create a MyAnalyticFuction and use this to project the solution
MyAnalyticFunction<Number> fobj2(fptr_shrt);
eq_sys.get_system("data").project_solution(&fobj2);
ExodusII_IO(mesh).write_equation_systems("example3_2.ex2", eq_sys);
