Function Documentation

dvariable betacf	(	const dvariable &	_a,
		const dvariable &	_b,
		const dvariable &	_x,
		int	MAXIT
	)

Incomplete beta function for variable objects.

Evaluates the continued fraction for imcomplete beta function.

Parameters:

_a
_b
_x
MAXIT	Maximum number of iterations for the continued fraction approximation in betacf.

Returns:

Incomplete beta function

The implementation of this algorithm was inspired by "Numerical Recipes in C", 2nd edition, Press, Teukolsky, Vetterling, Flannery, chapter 2
