gives the logarithm of the gamma function log Gamma(z).
  • Mathematical function, suitable for both symbolic and numerical manipulation.
  • LogGamma[z] is analytic throughout the complex z plane, except for a single branch cut discontinuity along the negative real axis. Log[Gamma[z]] has a more complex branch cut structure.
  • For certain special arguments, LogGamma automatically evaluates to exact values.
  • LogGamma can be evaluated to arbitrary numerical precision.
  • LogGamma automatically threads over lists.
