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

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*
