wireframe

This function plots a sub-sampled wireframe of a surface.

Description

This function generates undersampling of the mesh lines from the matrices usually passed to the SURF command. Highly resolved surfaces drawings often look better than there low resolution counterparts, but the high density of mesh lines can obscure surface details. Undersampling of the mesh lines can indicate important contour features, but must be done properly. The undersampling has to be performed carefully so that the mesh lines still track the surface features, something that is not obtained by simply rendering a lower resolution wireframe.

Its not a bad idea to undersample the gridlines. Large
plots can be totally obscured by the gridlines. From the
description I was hoping to see an intelligent agent that
would adaptively do this, perhaps even do so differentially
across the grid. Too much to ask, you must specify the
undersampling factor.

I was disappointed to see additional lines over my surface
though that clearly did not belong. The code also bombs
when x and y are passed as vectors for each axis, not as
arrays as the output of meshgrid. This is a valid way to
call surf, and is easily checked for and easily repaired with
a call to meshgrid.

Problems fixed. I might even lean to a 4.5 rating.
Intelligently automated undersampling of the grid lines
is not a trivial thing to do anyway. I still have hope
though...

EXCELLENT!!! Thanks for this, ive been wanting to do this for a while, often i have thousands of points so tend to get just a black surface if i try to include a grid! This does the job just nicely

Really good, does that it promises. Especially helpful when visualizing huge (accurate) grids.

Nice. If you want to quickly try it out:
x = [0:0.1:10];
y = [0:0.1:10];
z = sin(x)'*cos(y);
mesh(x,y,z); wireframe(x,y,z,5);
