77 //! the Function of type EvaluatorFunc2Var from Approx
78 //! must be a subclass of AdvApp2Var_EvaluatorFunc2Var

84 //! R[0,N-1] .... R[Num1DSS,N-1].... R[Dimension-1,N-1] for the Nth parameter
86 //! the order in which each Subspace appears should be consistent
87 //! with the tolerances given in the create function and the
88 //! results will be given in that order as well that is :
89 //! Surface(n) will correspond to the nth entry described by Num3DSS
