Hi,
I've attached the value of a particular func where it fails. But
this varies though. Also I restarted the code, making sure I evaluate
only the problematic part and it works. So, it must be an internal
memory limit for Maxima. Is there any way of increasing this? I've
searched through Maxima's documentation and couldn't find anything about
a memory limit.
