# Graphical representation of complex functions

Which software (preferably: free/open source) can one use to graphically represent a complex function? I know that real functions can be easily represented with Octave or R; what can you recommend for complex functions?

Thanks in advance, Lucian

The article "Phase Plots of Complex Functions" in the June 2011 AMS Notices may have some relevant information. –  Willie Wong Jul 24 '12 at 17:58
