Roots of polynomial

Hi all,

Is there a subroutine somewhere to find the largest positive real root of a polynomial? I am solving a polynomial of degree 5. I do not need other roots. The coefficients of the polynomial are REAL.

Thanks much.

One strategy you can try is to modify the appropriate routine(s)
of chapter 11 to calculate just the larges eigenvalue of you polynomial's comapnion matrix. Otherwise, you can try looking for such routines in the Web. (There's a lot of them floating around).
