Function Documentation

Bisect()

double Bisect	(	const std::function< double(double)> &	func,
		const double	a,
		const double	b,
		const double	eps
	)

Returns one solution for the equation \( func(x) = 0 \) with \( x \in [a,b] \).

The requirement \( func(a) > 0 > func(b) \) has to be fulfilled.

The solution is determined by bisection.

The input function func t has to be declared: double pp(double x); i.e., pp could be used as first argument in the parameter list when calling Bisect.

Parameters

[in]	func	function with one double input parameter that returns a double value
[in]	a	interval begin
[in]	b	interval end
[in]	eps	accuracy \( \varepsilon \)

Returns

solution \( x^\ast\) such that \( |func(x^\ast)| < \varepsilon \)

Warning

The function values \( func(a) \) and \( func(b) \) musst have different signs.
