Indeedn each time I run example_3d_affine, I got a Segmentation violation error. I can copy the last part of the report error here if it can help someone telling me what's wrong with my version or my manipulation :
Error in ==> gui_mainfcn>local_openfig at 216
gui_hFigure = openfig(name, singleton, 'auto');
Error in ==> gui_mainfcn at 94
gui_hFigure = local_openfig(gui_State.gui_Name, gui_SingletonOpt);
Error in ==> showcs3 at 29
Error in ==> example_3d_affine at 19
I will try to get a newer version of Matlab from my university, hope it will solve the problem.
