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*

I thank you very good

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
