1. Using the publisher from the editor window: Open the file spiralplot.m
that you created while working with Lesson 11. You can open the file by
following File ---> Open from the menu or from the command window with
either edit spiralplot .m or open spiralplot .m. Once the file is open in
the editor, select Publish from the File menu (see Fig. 2.17) of the editor
window, or click on the publish icon (next to the printer icon in the menu
bar). The script open in the editor will be published to an HTML file and
MATLAB will automatically open the HTML file for your perusal.

Figure 2.17: The MATLAB publisher can be invoked from the File menu when the
script is open in the editor window.
2. What are those cells? A cell, in a script file, is a set of commands enclosed
between two cell separators (lines that start with %%). You can execute a cell
independent of other cells. You can also execute one cell and then the next
by simply clicking on the cell execution option buttons (see Fig. 2.17) in the
toolbar of the editor. Move your mouse on these buttons to see what each
one does.
Now, open the spiralplot.m file again (if you have closed it) in the editor
and add the following two cells at the end of the file. You can just type %%
to start a new cell or click on the Insert Cell Divider button in the toolbar to
in:>crt it.
