Does anybody know why this code isn't running?
x = -4:4;
y = [0 .15 1.12 2.36 2.36 1.46 .49 .06 0];
cs = spline(x,y);
xx = linspace(-4,4,101);
yy = ppval(cs,xx);
plot(x,y,'o',xx,yy,'-');
I can't figure it out! Thanks.

Don't quite know what was going on there, yeah it does work fine. Sorry about that!
As an aside, I'm plotting the following but want the y-axis to start from 0. Is there a way to implement this into the code?
x = 1:-.01:0.90;
y = [13 17 17 18 18 25 25 24 24 26 46];
plot(fliplr(x),fliplr(y),'o');
set(gca,'XDir','reverse');
xlabel('n')
ylabel('\eta_{\infty}')
