As I see there are no specific plot commands for complex functions. There are 3 types that would be preferable: 1. parametric plot 2. contour plot 3. conformal plot
The parametric plot can be simulated with parametric_plot and the contour plot with contour_plot. However for these functions one have to specify the input as a pair of functions. When you have a complex function f, the input would be: (lambda z: real(f(z)), lambda z: imag(f(z))) The problem with this simulation is that f has to be computed twice to obtain the real and the imaginary part. If you have a very computation intensive function f this is deadly. So it would be great if the parametric_plot and contour_plot had an option for complex functions that would avoid these double computations. More generally parametric_plot and countour_plot could take a functions that returns a pair of values in addition to taking a pair of functions. Is this problem already recognized? I also would be willing to implement such a functionality if not.
