Well, no matter, here is an instant replay). If you want the code, take a look at Turbo Pascal Numerical Toolbox, and/or Press & Flannery & al, Numerical Recipes. If you just want a program for solving the roots, get /pc/ts/tsnum12.arc by anonymous ftp from uwasa.fi archives. ...................................................................
