In this particular example, it's cargo cult. Otherwise, it's a silly
hack for distinguishing function files from scripts. The way the
Matlab/Octave language works is that if the first statement is a
function definition, then that file is treated as a function file. The
1; is a trick to not make the first statement a function definition,
hence make the file is a script file. Here it's unnecessary because
the statement in that file immediately following the 1; is not a
function definition.

It's the argument (angle) of a complex number

Yes, Octave is such a resource. Type "help foo" to figure out what foo
