Subject: Finding the roots of a polynomial 22. ***** Q: How to find all roots of a polynomial? A: If you need the code, see Turbo Pascal Numerical Toolbox and/or Press & Flannery & Teukolsky & Vetterling (1986), Numerical Recipes, The Art of Scientific Computing, Cambridge University Press. The Numerical Recipes codes are available as /pc/turbopas/nrpas13.zip (big, 404k!). If you just need to solve such a task (without code available), get ftp://garbo.uwasa.fi/pc/ts/tsnum12.zip (or whatever version number is the latest) from garbo.uwasa.fi archives by anonymous FTP or mail server. --------------------------------------------------------------------
