virtual RCP<const Basic> SymEngine::TwoArgBasic< BaseClass >::create

The polygamma function

It is a meromorphic function on \mathbb{C} and defined as the (n+1)-th derivative of the logarithm of the gamma function:

.. math:: \psi^{(n)} (z) := \frac{\mathrm{d}^{n+1}}{\mathrm{d} z^{n+1}} \log\Gamma(z).
