Cartoon of a magnon wave in 1- or 2D 

Cartoon of a magnon wave. Option to generate 1- or 2D version. 

Note that in addition to the main matlab code, there is the function mArrow3.m used to generate fancy 3D arrows, which I downloaded from MathWorks File Exchange, and for which I credit Georg Stillfried. I use this function in several of the matlab codes available here.
