input impedance converter : S11, Z, Y (1 complex value)

03 Jun 2005 (Updated 02 Mar 2010)

Code covered by the BSD License

reflection coef. converter: S11 -impedance -admittance -Return Loss -VSWR; graphical & text input

File Information
Description	SZYconv is a quick 1-port 1-value S-parameter converter it converts between various representations of a complex reflection coefficient : - GAMMAIN (complex normalized to 50 ohms) in either MA or RI - Z, Y of the corresponding load connected in shunt - RL, VSWR (using the current angle) input & output in both text or graphical form (by clicking on a polar chart); toggable grids (smith Z, smith Y, polar) still included older version 1.1, it works starting with matlab 4.2*
MATLAB release	MATLAB 7.5 (R2007b)
Other requirements	none; version 2.0 (2007b) is the latest, also included older version 1.1 developed in matlab 4.2* and tested in R12, R14, R2007a,b, works fine (no toggable grid); enjoy

07 Jun 2005	b keane	does what is says it does, nice and small; for all those times when you don't feel like firing up your simulator to convert a few complex values;... I would like to be able to switch the grid to smith Z and smith Y
06 Oct 2005	brain johnson	excellent

Updates
17 Dec 2007	added RL and WSWR as inputs
27 Apr 2009	v. 2.0 - 27.04.2009 > added smith chart grids (Z and Y) > made all grids toggable (smith Z and Y, polar) > better help/intro
02 Mar 2010	BSD license added
