Function Documentation

df1b2variable betacf	(	const df1b2variable &	a,
		const df1b2variable &	b,
		double	x,
		int	MAXIT
	)

Incomplete beta function for df1b2variable 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
