beta
|
beta(z,w)
returns the beta function gamma(z)gamma(w)/gamma(z+w)

ln_gamma,
bico
|
bico
|
bico(n,k)
returns the binomial coefficient n!/(k!(n-k)!) as a double.

ln_gamma,
beta
|
erfc_nr
|
erfc_nr(x)
returns the complementary error function 1-erf with fractional
error less than 1.2e-7 everywhere.
|
ln_gamma
|
ln_gamma(z)
returns natural log of the gamma function.
Error is less than 1e-13 for real part of z>=1.
Use lngamma if you know that all z>=1, or if you don't care much about
accuracy for z<1.

|
lngamma
|
lngamma(x)
returns natural log of the gamma function.
Error is less than 1e-13 for real part of x>=1.
Use ln_gamma if some x<1.
