convert x and y vector to meshgrid

I have an x, y, and z vector that I am curr开发者_运维技巧ently using to create a 3-D scatter plot. Is it possible to create a mesh plot using these three vectors? I would prefer to only use these vectors and not alter any of my previous code.

I'm a bit confused by your terminology, but I'm assuming that you have unstructured surface data - z is the surface height for a set of positions x, y.

If you want to form a "mesh" for this data you could triangulate (via a Delauany triangulation of the positions):

t = delaunayn([x, y]);

If you want to visualise the "meshed" surface you can use trimesh/trisurf:

figure;
trimesh(t, x, y, z);
