Hi, I just got trial Matlab/Simulink in order to trial Waveform_Generator GUI for my projects. When I run it the window shows for a moment then vanishes. If I knew code I'd fix the errors but I do not. Make the app work and I'll buy Matlab. Thanks.

Hi, I just got trial Matlab/Simulink (the requirements for the app) in order to trial Waveform_Generator GUI for my projects. When I run it the window shows for a moment then vanishes. If I knew code I'd fix the errors but I do not. Make the app work and I'll buy Matlab. Thanks, Pahl
