Function/Subroutine Documentation

real(wp) function moments_module::beta_function	(	real(wp), intent(in)	z,
		real(wp), intent(in)	w
	)

Beta function.

This function evaluates the beta function B(z,w). This is the name used by Legendre and Whittaker and Watson (1990) for the beta integral (also called the Eulerian integral of the first kind).

Parameters

[in]	z	first parameter of the beta function
[in]	w	second parameter of the beta function

real(wp) function moments_module::gammln

(

real(wp)

xx

)

Gamma function logarithm.

This function returns the logarithm of the gamma function, gammaln(A) = log(gamma(A)). Input must be nonnegative and real. Converted from Numerical Recipes.
