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