is there a facility to plot the entries of a complex matrix (recent
gretl feature) in the cartesian plane? Similar to what is built-in as
the plot of the VAR roots, but for arbitrary input and in other contexts.
OK I'm halfway there; we can just plot the imaginary part against the
real part of course. For a given complex column vector e I tried the
matrix twocol = cswitch(e, 2)
gnuplot 2 1 --matrix=twocol --output=display
What I'd like to add as an option is the unit circle, but I don't know
how to combine that with the matrix option.
