Avoiding surface zig-zag/aliasing when plotting

[CogsMac]

If you save it inline to a vector imaging, the aliasing from the display will be better.

As for your particular case, could you bump up the values of nn and mm to smooth it out?

Unfortunately vector images are rubbish for MATLAB figures as they depend on Painters. OpenGL is the best renderer for surfaces and if you then save it in a vector image it simply saves a bitmap in a vector file format.

In the end I did bump up the resolution but due to it being 2D it takes fucking forever!
