Setting Edge Color for Large Surface Plots

(Originally posted on Doug's MATLAB Video Tutorials blog.)

Often if you make a surface plot with SURF for a large dataset, it will appear all black because MATLAB is trying to draw all the edge lines. You can stop these lines from obscuring your data by turning the edge color off:

a= peaks(1000);

h = surf(a);

set(h, 'edgecolor','none')
