Hello everyone)

I want to change the value of constant block in Simulink from 0 to 1 and vice versa using push button in GUI.

function pushbutton2_Callback(hObject, eventdata, handles)

c=1

set_param('opc/Constant','value',num2str(c))

Could you explain more on what is working and what is not?

Your code snippets look correct. Maybe you have to open/load the model first.

load_system('opc'); % or open_system('opc','loadonly')
