When Function is subclassed in python, we overload eval, for example:

    def eval(values,x):
        values[0] = sin(x[0])*cos(x[2])

To be able to hand 'eval' a numpy.array with the right dimension we have used 
Function::geometric_dimension(). 

This is all done in the 

  %typemap(directorin) double* x {

typemap. Any equivalent function will do.
