## Detailed Description

constructor from the trivial function with two argument

double func( const double , const double ) ;
const AbsFuction& fun = Adapter2DoubleFunction( fun ) ;
// evaluate the function in point (1,2):
Argument arg(2) ;
arg[0] = 1 ;
arg[1] = 2 ;
double value = fun( arg ) ;

Parameters

  func | pointer to trivial function
