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
