Yes, I understand that, and I always watch for the output of my own
algorithms for them to not produce such things. But currently I'm
working with some experimental data array which has some gaps (probably
because of data loss in the past or equipment reparation). So now I
have no choice: I have to work with this kind of array because it's
simply the only data record I have.
