I didn't know this kind of end before. I remembered that matlab seems
support omitting the first or the last element inside indexing
expressions when I used it many years ago, for example, a(:5), a(2:).
these are not supported in octave. but octave support omitting both
the start and the end of the indexing expression at the same time,
i.e. a(:). Mentioning this, I am a little curious why a(:) and
a(1:end) are (should be?) different for row vectors. I know the former
one is frequently used to reshape matrices. Is this just an issue of
compatibility? will the reshaping with a(:) be deprecated in the
future?
