The Value is the index down into the menu, not the content of the line you selected. allvalues = get(handles.popupmenu1,'String'); choiceidx = get(handles.popupmenu1,'Value'); if iscell(allvalues) choicestr = allvalues{choiceidx}; else choicestr = allvalues(choiceidx,:); end choice = str2double(choicestr); set_param('mymodel/lockout','Value',choice);

I am getting an error ??? Error using ==> GUI>pushbutton1_Callback at 119 Invalid setting in Constant block 'lockout' for parameter 'Value'.

Sorry, I don't know Simulink and models at all, and so have no idea what kind of value needs to be used in set_param for that parameter. Possibly passing it choicestr instead of choice would work... I don't know. If your choices are not numeric then you certain do not want the str2double step. |
