crgamma() doublecomplex crgamma ( doublecomplex  z ) Reciprocal of gamma function 1/Γ(z) (complex argument) Purpose crgamma computes the reciprocal of the gamma function at a complex number z. Returns Reciprocal of the gamma function 1/Γ(z). Parameters [in] z Argument z. (z != 0 and z != negative integer) Error handling If z is zero or real negative integer, domain error (EDOM) is reported. Range error (ERANGE) may occur.
