Hi everyone, I was trying to graph some functions of a complex variable on mathematica 9, but without success.. so I googled a little bit and found this helpful guide including various graphs of the Gamma funcion. http://mathworld.wolfram.com/notebooks/SpecialFunctions/GammaFunction.nb
So I tried to enter the commands suggested by the guide in Mathematica 9 (hoping to obtain some graphs) and nothing... seems mathematica 9 doesn't recognise at all commands like  "ComplexPlot3D" or "ComplexContourPlot".
In particular i need to graph this complex function: y=e^z and f(z)=((z^2-1)(z-2-i)^2)/(z^2+2+2i)

Thankyou very much !
