Symbol: MeromorphicDerivative — dzdf(z) — Complex derivative, allowing poles
The call syntax for this operator is the same as for Derivative.
This operator is equivalent to ComplexDerivative except that whereas ComplexDerivative is undefined at a pole, MeromorphicDerivative gives UnsignedInfinity ( ∞~ ) at a pole.
