bisection()

double umontreal.ssj.util.RootFinder.bisection ( double a, double b, MathFunction f, double tol )

static

Computes a root \(x\) of the function in f using the bisection method.

The interval \([a, b]\) must contain the root \(x\). The calculations are done with an approximate relative precision tol. Returns \(x\) such that \(f(x) = 0\).

Parameters

a	left endpoint of initial interval
b	right endpoint of initial interval
f	the function which is evaluated
tol	accuracy goal

Returns

the root \(x\)

brentDekker()

double umontreal.ssj.util.RootFinder.brentDekker ( double a, double b, MathFunction f, double tol )

static

Computes a root \(x\) of the function in f using the Brent-Dekker method.

The interval \([a, b]\) must contain the root

\(x\). The calculations are done with an approximate relative precision tol. Returns \(x\) such that \(f(x) = 0\).

Parameters

a	left endpoint of initial interval
b	right endpoint of initial interval
f	the function which is evaluated
tol	accuracy goal

Returns

the root \(x\)
