Question

I need to scale the axes of a convolution function after plotting successive convolutions of x with itself. How do I scale the x axis for each so it has the correct support and how do I scale the convolutions to show that they are density functions?
x=ones(1,20); con0=conv(x,x); con1=conv(x,con0); figure(1); plot(con0); figure(2); plot(con1); Thanks in advance!
