Not at all, thanks for the additional details, Tom.

Somewhere I have copies of IEEE tutorial articles on this sort of generalized
circuit theory... they ended up as references for work I did in college. (We
spent the bulk of our time worrying about scattering parameter matrices,
however. I did write some Matlab code to do n-port conversions between S, Y,
and Z parameters, though -- but based off of formulas from papers: I question
if I could have correctly derived the conversions between, e.g., S and Y
myself in a reasonable period of time, since the port terminations for the
scattering parameters were allowed to be arbitrary at each port and the math
for this requires a decent background in linear algebra.)
