FindRoot


Name:
FindRoot - numerically find a root in an interval
Synopsis:
proc double1 double2 double3 FindRoot -> double  
Examples:
 
cout 15 setprecision % for display only
{dup mul 2 sub} -3.0 7.0 0.00000000001 FindRoot
Description:
 
Numerically searches for a root of a function
specified by proc in the interval [double1, double2].
The search stops when the absolute value of proc
is less or equal double3.
Parameters:
 
Bugs:
 
- should raise error when there is no sign reversal
- tracing should be optional
- specification of precision should be optional
Remarks:
 
FindRoot currenly supports only a single method for
root finding: the "bisection method" (see [2]). The
Mathematica implementation uses different methods (see [1]).
