Well, in Perl (and, I guess, in PCRE used by Octave) '.' matches any
character, so, say, the following

$s =~ m/^.{3}(.{4}).{5}(.{6})/;
#              $1        $2

skips 3 character from the beginning, then matches 4 characters and puts
them into $1, then skips 5 characters and then matches 6 characters and
puts them into $2.

I am not that familiar with Octave RE syntax; I hope the above can easily
be translated.
