Release of VEMLab v2.2

VEMLab: a MATLAB library for the virtual element method Release of VEMLab v2.2 >>  From VEMLab v2.1 to VEMLab v2.2: Fix disp() in plot_and_ouput_options.m: disp(“Hello”) seems to work only in newer versions of MATLAB. So, it is changed to the standard MATLAB format disp(‘Hello’). Results that are postprocessed in the graphical user interface of GiD…
