Analyzing the real part of the roots

For some applications it may be interesting to determine if a polynomial in a set defined by a parametric polynomial has the real part of one of its roots equal to a pre-defined value. This may be done by using the procedure

 
int ALIAS_Is_Root_RealPart(int Degree,  
           int NbParameter,
           int HasInterval,
           INTERVAL_VECTOR (* TheCoeff)(INTERVAL_VECTOR &), 
           INTERVAL_VECTOR (* TheCoeffCentered)(INTERVAL_VECTOR&,double a), 
           int Iteration,
           INTERVAL_VECTOR &Par,
           double *Root,
           INTERVAL_VECTOR (* EvaluateComplex)(int,int,INTERVAL_VECTOR &),
           int (* Simp)(INTERVAL_VECTOR &))
where
