Usage: 
(1) plotsmithchart(Zl,Zo) 
Where Zl is the Load Impedence (possibly complex) and Zo is the Characteristic Line Impedence. Plots a smith chart, along with the reflection coefficient circle and the line of intersection with resistive component equal to 1.
(2) plotsmithchart 
Without any parameters draws a blank smith chart. Wavelengths toward the generator are labeled around the perimeter.
Example calls: 
(1) plotsmithchart(25,50) 
Draws a smithchart,calculates and plots the reflection coefficient for a characteristic impedence of 50 ohms and a load impedence of 25 ohms.
(2) plotsmithchart(50+50j,75) 
Same as (1) with a load impedence of 50+50j ohms.
(3) plotsmithchart 
Plots a blank Smith Chart.
