Install Ted Ersek's package RootSearch from:

http://library.wolfram.com/infocenter/MathSource/4482/ 

I don't know why Wolfram doesn't acquire the rights to this package and
incorporate it as part of regular Mathematica. Finding all the roots of a
real function on a 1-dimensional domain is the most common case of root
finding, and it is the one thing regular Mathematica is very poor at. Ted's
package is quite robust and returns all the roots in order.

Hi,

Is there a command for numerically finding all roots of a function in a 
given interval. If not, what's the best way of accomplishing this task?

Many thanks in advance,

Sam
