FZero Class

FZero finds a zero of the function in the given interval. Repeated roots are not found, FZero can find only bracketed single roots.

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 one root of f within the given interval.
Public methodFind(OneVariableFunction, Double) Finds one root of f near the starting guess, x0.
Public methodFind(OneVariableFunction, Double, Double) Finds one root of f within the given interval.

Remarks
Based on the
C#
zeroin()
root finder published originally in Computer Methods for Mathematical Computations by Forsythe, Malcolm and Moler in 1977. This class is similar to MATLAB's FZero function.
