Ah, then that's the generic ban against deleting objects inside a
loop:
this is the price to be paid for certain optimizations of the gretl loop
code. If we're to "quasi-compile" loops we can't have objects popping
out of existence as the iterations proceed.
Ah, ok! Thanks for clarification, Allin. I am totally fine with this
decision.
The nearest acceptable equivalent would be
case1 = {}
to reduce the matrix in question to an empty one (0 x 0), hence freeing
up almost all of the memory allocated to it.
Yes, indeed.
Best,
Artur
