Could you please share some hints as how are they to be used? The docs
are a bit too concise for my taste: what is "DIMS" supposed to be? What
about "S1, ..., SN"? I've started to use indexing heavily as of late,
but have been unable to use sub2ind and ind2sub, I tipically get an
"index out of range" error (see )
