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