PCBWriter
Create PCB board definitions from 2-D antenna designs
Description
Use the PCBWriter

Use the gerberWrite
function to generate gerber files from the antenna design files. Send the generated files to the Mayhew writer manufacturing service.
gerberWrite(PW)
The default folder containing the gerber files is named "untitled" and is located in your MATLAB folder. Running this example automatically opens up the Mayhew Labs PCB manufacturing service in your internet browser.
Drag and drop all your files from the "untitled" folder.
