Hello.  No, google doesn't seem to recognize nonalphanumeric characters.
Also, the mailing list archive at www.octave.org seems to change the
symbol to `at' to obfuscate e-mail addresses.  See, e.g.,

http://www.octave.org/octave-lists/archive/bug-octave.2004/msg00522.html


The symbol @ is the operator to create a function handle; googling on
"function handle" and octave is more successful.

Briefly, for example, to find pi as a root of sine:

octave> f = @ sin;
octave> fzero (f, [2, 4])
ans = 3.1416
octave> 

Hope this helps.
