104 The difference between @code{triplot} and @code{trimesh} is that the 104 @DOCSTRING(trisurf)
105 former only plots the 2-dimensional triangulation itself, whereas the 105
106 second plots the value of some function @code{f (@var{x}, @var{y})}. 106 The difference between @code{triplot}, and @code{trimesh} or @code{triplot},
