Hi Ole,

Thank you, I was considering trying Mathcad or Cadabra or Axiom but now
that you recommend it for sure!

I seem to recall the Mathematica I used to use of a friend a long time
back who was a math professor required about a 500 dollar add on for
impedance and reactance network modeling, does Mathcad require
additional packages also?
