These are the files generated using Matlab's diary command.
In general, don't try to execute these. If you want to try out the
different commands, extract them from the diary file. They have been
slightly edited in two ways:
to cut down on non-informative lines, such as when I accidentally
displayed the results of
x = linspace(-1, 1, 100000)
by omitting the semicolon at the end.
to insert a few comments, since the commands are shown but the
reasoning behind them is not in the text.
