To be able to edit code and run cells, you need to run the notebook yourself. Where would you like to run the notebook?

In the cloud (experimental)

Binder is a free, open source service that runs scientific notebooks in the cloud! It will take a while, usually 2-7 minutes to get a session.

On your computer

(Recommended if you want to store your changes.)

  1. Copy the notebook URL:
  2. Run Pluto

    (Also see: How to install Julia and Pluto)

  3. Paste URL in the Open box

Frontmatter

If you are publishing this notebook on the web, you can set the parameters below to provide HTML metadata. This is useful for search engines and social media.
