The false position method for finding roots of functions.

For a list of all members of this type, see FalsePositionRootFinder Members.

System.Object

      numerics4net.root.FalsePositionRootFinder

Thread Safety

Public static (Shared in Visual Basic) members of this type are safe for multithreaded operations. Instance members are not guaranteed to be thread-safe.

Remarks

For example, to find roots for sine, first a Function delegate is defined:

Function sine = new Function(Math.Sin);

Then, a root finder is created using the function delegate:

FalsePositionRootFinder finder = new FalsePositionRootFinder(sine);

Lastly, locating roots is accomplished using the FindRoot method:

// find the root between 3 and 4.
double pi = finder.findRoot(3.0, 4.0);

// find the root between -1 and 1.
double zero = finder.findRoot(-1.0, 1.0);
