Hello, I require the computation of ln of the gamma function for all negative non-integer values. The reflection formula can be used for half of the negative non-integers along with the log since for half the values will be positive. However, I would like to obtain a value for the other half. I'm using the ln of gamma as an intermediate step after which I raise the result with an exponential, so that ultimately I am not after the actual value of ln gamma itself. I am open to any methods that work.
At the current time the only way that I've found to compute the ln of gamma for negative non-integer values is to treat the argument as a complex number z = -x + 0i and then use Ln(z) = ln(|z|) + iPI, for the term involving the sin from the relfection formula. I'd appreciate help and suggestions. Thanks, Marc. _______________________________________________ Help-gsl mailing list [email protected] http://lists.gnu.org/mailman/listinfo/help-gsl
