Answer 1

You have use the handles to the subplots and plots:

h(1)=subplot(221);
    p(1)=plot(rand(10,1));
h(2)=subplot(222);
    p(2)=plot(rand(10,1));
h(3)=subplot(223);
    p(3)=plot(rand(10,1));
h(4)=subplot(224);
    p(4)=plot(rand(10,1));


set([h(2) p(2)],'visible','off')

hides the 2nd plot. @Jonas answer seems more complete however. It's certainly easier, because you don't have to collect the children yourself manually as I did here.
