## Detailed Description

constructor from the trivial function with two argument

      double func( const double , const double , const double ) ;

      const AbsFuction& fun = Adapter2DoubleFunction( fun ) ;

      // evaluate the function in point (1,2,3):
      Argument arg(3) ;
      arg[0] = 1 ;
      arg[1] = 2 ;
      arg[2] = 3 ;

      double value = fun( arg ) ;

Parameters:

  | func | pointer to trivial function
