Properties
 NameDescription
Public propertyError Gets the error associated with the root just computed.
(Inherited from RootFinderBase)
Public propertyIterations Gets the number of iterations used computing the last root.
(Inherited from RootFinderBase)
Public propertyMaxIterations Gets and sets the maximum number of iterations used in finding roots.
(Inherited from RootFinderBase)
Public propertyMaxIterationsMet Returns true if the root just computed stopped because the maximum number of iterations was reached; otherwise, false.
(Inherited from RootFinderBase)
Public propertyTolerance Gets and sets the error tolerance used in finding roots.
(Inherited from RootFinderBase)
Public propertyToleranceMet Returns true if the root just computed stopped because the error tolerance was reached; otherwise, false.

Methods
 NameDescription
Public methodBracketRoot Attempts to bracket a root given the function and an initial guess near a suspected root.
(Inherited from RootFinderBase)
Public methodClone Creates a deep copy of this root finder.
(Overrides RootFinderBaseClone)
Public methodFind(OneVariableFunction, Interval) Finds a root of the given function within the given interval.
Public methodFind(OneVariableFunction, Double, Double) Finds a root of the given function within the given interval.

Fields
 NameDescription
Protected fielderror_The current error.
(Inherited from RootFinderBase)
Protected fielditer_The current number of iterations performed.
(Inherited from RootFinderBase)
Protected fieldmax_The maximum number of iterations.
(Inherited from RootFinderBase)
Protected fieldtolerance_The error tolerance.
(Inherited from RootFinderBase)

Remarks
Ridders' Method first evaluates the function at the midpoint of the interval, then factors out the unique exponential function which turns the residual function into a straight line.
