Hello, I have a complex function like this f : z -> f(z) and I wonder how can I plot this because z is complex and f(z) as well. Any suggestions ? Thank you very much !

It depends on what you want to do.
To plot the real and imaginary parts as a function of ‘z’:
plot(z, real(f(z)), z, imag(f(z)))
to plot the real and imaginary parts against each other:
plot(real(f(z)), imag(f(z)))

You did not say how you want to plot them.
Try this:
plot(real(z), real(f(z)), imag(z), imag(f(z)))
or some version of it to get the result you want.
You can also plot the absolute values (magnitudes) against each other with the abs function, and the phase angles with the angle function.
The possibilities are myriad, if not infinite.
