Loadable Function: z = gsl_sf_fact (arg1)
Loadable Function: [z, err] = gsl_sf_fact (…)

Computes the factorial n!. The factorial is related to the Gamma function by n! = \Gamma(n+1). The maximum value of n such that n! is not considered an overflow is 170.

err contains an estimate of the absolute error in the value z.

This function is from the GNU Scientific Library, see http://www.gnu.org/software/gsl/ for documentation.
