While tinkering with a notebook that loads a large chunk of data in memory, I noticed that if I run it multiple times, the past chunks reside in memory. I understand that the reason (or one of) for which this happens is that the past output mechanism (%
) keeps a reference to them, so they cannot be garbage collected.
Is there a way to explicitly make Mathematica forget some data?
$HistoryLength = 0
for instance. $\endgroup$
