EngNote - Polarization

"EngNotes" are my engineering notes.  This is my way of creating a digital version of an engineering notebook.  This particular entry is on Polarization.
Textbooks and online references often don't give a complete and practical discussion of how to calculate the impact of a wave's polarization on the magnitude and phase of a received signal.  As a result, I made a polarization toolbox for Matlab to serve as a quick reference.  There is a link to the toolbox in the Code section below.
