What is the c++ code to convert the result of interpolation
on a discrete vector ?

 class IdentityDef : public Function
  {
  public:

    IdentityDef(Mesh& mesh) : Function(mesh) {

    }

    void eval(real* values, const real* x) const
    {
      values[0] = x[0];
      values[1] = x[1];
      values[2] = 0;
      values[3] = 0;
    }

  };

  IdentityDef phi(mesh);
 uBlasVector phiv(phi.vector().size());
  phiv=phi.vector();


the compilation is ok but
it fails to run cause the .vector() function
works only on discrete function,

I tried also to heritate DiscreteFunction on IdentityDef
that doesn't work the same. Sorry I'm used to freefem++
where these distinction between variable does not exist.
