Plotting complex functions

[Børge Strand-Bergesen]

Hi,

I need to plot the complex function H(w) on three axis, Re, Im and w.
This comes very close to the example at

which I found on

How should I create something like this in Octave?

Once plotted, is it feasible to zoom in and out and pan the plot?


Thanks,
Borge
