Spline Interpolation Code Error

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.

Works fine for me.

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}')

Figured it out.

No worries
