Directions on how to use RLocusGui and interpret the results are in RLocusGui.html.  To use the RLocusGui tool you need two files.  These are:

  1. RLocusGui.m    :    The GUI code.
  2. RLocusGui.fig   :    The GUI graphics.

Both of these files must be on you hard disk so that they are in the MATLAB® path.  Download them and save them so that MatLab can find them (from the Matlab menu go to File->Set Path and include the directory where you stored the files.)  

The files Zipped:

All three files (RLocusGui.m, RLocusGui.fig) zipped in RLocusGui.zip.
