Try it in Matlab?

Right now when I try to get help in Matlab, I'm taken to this page.

I need to be at a page where I can click a button that says "Try it in Matlab" wondering how I can do this?

Try this page: Finding the Length of a Pendulum in Motion

It seems to have what you want, or at least it did when I accessed it just now.
