Although this function generally does what it states, it is limitated on several aspects: most obviously, it can not handle a moderately large [a] input. for instance, try a = randn(5000);
another thing that make me dubious on using this function is it is quite slow, when [a] is within-the-limit large.
Overall, I don't recommend it.

What I like about this submission is that it handles finding multi-dimensional patterns in multi-dimensional data. Some guru might be able to vectorize it a bit but it works fine as it is.
