Let be the roots (either complex or real) of
a polynomial of degree . Let be:
This procedure enable to compute the elements
( is the sum of the roots, the product of the roots).
The syntax is:
VECTOR ProdN_Polynomial_Interval(int Degree,VECTOR &Coeff)
This procedure returns 0 if the leading coefficient is equal to 0, 1
There is an equivalent procedure for interval polynomial:
- Degree: degree of the polynomial
- Coeff: coefficients of the polynomial ordered along
INTERVAL_VECTOR ProdN_Polynomial_Interval(int Degree,INTERVAL_VECTOR &Coeff)
which returns intervals including the .
This procedure returns 0 if 0 is included in the leading interval.
