+%SINGLEPATCH Concatenate patches to be plotted as one
+%
+% [xp, yp, zp, ...] = singlepatch(x, y, z, ...)
+%
+% Concatenates uneven vectors of x and y coordinates by replicating the
+% last point in each polygon.  This allows patches with different numbers
+% of vertices to be plotted as one, which is often much, much more
+% efficient than plotting lots of individual patches.  
+%
+% Input variables:
+%
+%   x:   cell array, with each cell holding a vector of coordinates
+%        associates with a single patch.  The input variables must all be
+%        of the same size, and usually will correspond to x, y, z, and c
+%        data for the patches.
+%
+% Output variables:
+%
+%   xp:  m x n array of coordinates, where m is the maximum length of the
+%        vectors in x and n is numel(x).
