Matlab Circle Gcode Maker

I needed a way to generate Gcode to tell my Makerbot to move in circles, so I wrote a Matlab script to do so. The script has various parameters that control the code that is generated.

The result of the script is Gcode telling the machine to move in circles (or elipses) of increasing speed.

The code's messy, and single use, but I thought I'd post it in case someone else wanted to make Gcode draw circles :-)

circles.gcode is the file generated when all settings are set to their defaults.
