The RegulaFalsiSolver type exposes the following members.
The regula falsi method, also called the method of
false position, is a root
bracketing algorithm. It works by approximating the
target function by a line. The bracketing interval is
divided at the point where this line crosses the axis.
The regula falsi method is superior to the
bisection method in that
it will, in most cases, converge faster. However, in certain
situations it can get 'stuck,' and convergence may actually
be slower than the bisection method.
The Dekker-Brent method
combines the best of both worlds.
RegulaFalsiSolver inherits from
RootBracketingSolver, which in turn inherits
All properties of IterativeAlgorithm are available.
The AbsoluteTolerance and
RelativeTolerance properties set the desired
precision as specified by the
ConvergenceCriterion property. The default
value for both tolerances is
10-8). MaxIterations sets the
maximum number of iterations.
The TargetFunction property is a
function of one variable that specifies
the function we want to find a root for.
The LowerBound and
properties specify the bounds of the bracketing interval.
The target function must have a different sign at each
end of this interval.
The Solve(Double) method performs the actual
approximation of the root. This method returns the
best approximation that was found. The
Status property indicates
whether the algorithm was successful. The
EstimatedError property gives an upper
bound for the difference between the approximated and
the actual root.
