-## usage: [xx, yy] = meshgrid (x, y)
-##
-## Given vectors of x and y coordinates, return two matrices corresponding
-## to the x and y coordinates of a mesh.  The rows of xx are copies of x,
-## and the columns of yy are copies of y.
-##
-## [xx, yy] = meshgrid (x) is an abbreviation for [xx, yy] = meshgrid (x, x).
-##
-## See sombrero.m for an example of using meshgrid.
