MATLAB: Does ‘surf’ command cause MATLAB to hang or run slowly

Question

I've upgraded from matlab 2015a to 2017a, in 2017a the surf command causes matlab to hang.

Answer 1

This issue is likely because MATLAB is using 'painters' renderer to render 3D graphics.

Change the default renderer to opengl by executing this command:

>> set(0, 'DefaultFigureRenderer', 'opengl');

Please also check the startup.m file to verify if the 'DefaultFigureRenderer' is mistakenly set to 'painters'.
