Functions | |
double | gammln (double xx) |
Returns the value ln[?(xx)] for xx > 0. | |
double | gammp (double a, double x) |
Returns the incomplete gamma function P(a, x). | |
double | gammq (double a, double x) |
Returns the incomplete gamma function Q(a, x) ? 1 ? P(a, x). | |
void | gser (double *gamser, double a, double x, double *gln) |
void | gcf (double *gammcf, double a, double x, double *gln) |
Returns the incomplete gamma function Q(a, x) evaluated by its continued fraction representation as gammcf. Also returns ln?(a) as gln. | |
