David Park posted a message on 10 March, 2010 where he mentioned using my RootSearch package for problems such as finding roots of Mathieu functions. David was right that RootSearch is very good at finding zeros where a function does not change sign. If you have a specific example that is a problem send me an email at ( Ted.Ersek at navy.mil ) and I will trouble shoot. David was also right that the message about setting $MinPrecision to (-Infinity) can be ignored. I am almost finished with an upgrade to the package that accounts for several changes in Mathematica since the package was last updated. I expect to have the new package posted on MathSource within a week. You can always find the package by searching for "RootSearch" at http://library.wolfram.com/ Regards, Ted Ersek Get my popular Mathematica Tips and Tricks from http://library.wolfram.com/infocenter/MathSource/4557/ Note: My Tips, Tricks are still relevant, but haven't been updated since May, 2004.
