Hello colleagues, i couldn't track down, where the Nonsense applies, but in general (also in Matlab) it's better for organizing the data in a fixed array and track down, what you access from that. This helps the computer/language system.
However, it's not fully uncommon to formulate algorithms that reduce/consume an array in an iterative way and it's just easier to read, if the non-content is discarded. So this helps the reader or author of software. Implementation for the first is straight forward. Implementation for the second is (and will be) under discussion as general CS topic...
