| 21 ## Plot a surface and contour given matrices @var{x}, and @var{y} from | |
| 22 ## @code{meshgrid} and a matrix @var{z} corresponding to the @var{x} and | |
| 23 ## @var{y} coordinates of the mesh. If @var{x} and @var{y} are vectors, | |
| 24 ## then a typical vertex is (@var{x}(j), @var{y}(i), @var{z}(i,j)). Thus, | |
| 25 ## columns of @var{z} correspond to different @var{x} values and rows of | |
| 26 ## @var{z} correspond to different @var{y} values. | |
