tuple_lgammatuple_lgammaTupleLgammaTupleLgammatuple_lgamma (Operator)
Name
tuple_lgammatuple_lgammaTupleLgammaTupleLgammatuple_lgamma — Compute the logarithm of the absolute value of the gamma function of
a tuple.
Signature
Herror tuple_lgamma(double T, double* LogGamma)
Herror T_tuple_lgamma(const Htuple T, Htuple* LogGamma)
def tuple_lgamma(t: MaybeSequence[Union[float, int]]) -> Sequence[float]
def tuple_lgamma_s(t: MaybeSequence[Union[float, int]]) -> float
Description
tuple_lgammatuple_lgammaTupleLgammaTupleLgammatuple_lgamma computes the logarithm of the absolute value of
the gamma function of the input tuple TTTtt (for the definition
of the gamma function, see tuple_tgammatuple_tgammaTupleTgammaTupleTgammatuple_tgamma). It is defined for
every real number except for nonpositive integers. The logarithm of
the absolute value of the gamma function is always returned as a
floating point number in LogGammaLogGammaLogGammalogGammalog_gamma. The logarithm of the
absolute value of the gamma function of a string is not allowed.
Exception: Empty input tuple
If the input tuple is empty, the operator returns an empty tuple.
HDevelop In-line Operation
HDevelop provides an in-line operation for tuple_lgammatuple_lgammaTupleLgammaTupleLgammatuple_lgamma,
which can be used in an expression in the following syntax:
LogGamma := lgamma(T)
Execution Information
- Multithreading type: independent (runs in parallel even with exclusive operators).
- Multithreading scope: global (may be called from any thread).
- Processed without parallelization.
