Letbe univariate polynomials with rational coefficients andbe the ideal they generate. Assume that we are given approximationsfor the common roots. In this study, we describe a symbolic-numeric algorithm to construct a rational matrix, calledHermite matrix, from the approximate rootsand certify that this matrix is the true Hermite matrix corresponding to the roots. Applications of Hermite matrices include counting and locating real roots of the polynomials and certifying their existence.
