Notebook downloads need a free account. Once you are signed in, the download button on Gerchberg-Saxton algorithm in NumPy: a phase-only hologram for 25 spots gives you py-gerchberg-saxton.ipynb, executed, with the library versions it ran with.

The tutorial itself, with all its code to copy, stays open to everyone. The account also keeps your collections and your done marks.
