Can I use whether or not a function runs as a conditional statement?

I need some commands to execute if a pushbutton is pressed while certain other conditions are true. How can I write in a conditional statement "if y and z are true(conditions) and some function has run, then execute these commands" in coding form? This is in a GUI by the way if that helps.

this is a short example ; if the first condition is true :

x= 2 ; y = 3;

if (x+y)>4

disp x , disp y

else x-y

end

********************** now if the first condition is wrong :

if (x+y)> 5

disp x , disp y

else x-y

end

So I get that but here's the code in question

if handles.pushbutton2.BackgroundColor == [1 0 0] && handles.pushbutton2.String == 'push me' && pushbutton1_Callback(hObject, eventdata, handles) 

        handles.pushbutton2.BackgroundColor = [1 1 1];
        handles.pushbutton2.String = '         ';

So basically when the function runs it means pushbutton1 was pushed and I need that to cause a command to execute.
