Is there any way to unload unused module?

I've been testing how many modules can be loaded to erlang. I came up to
little less than 750 modules of 217.5 KB each. So beam.smp consumed 800
MB of memory.

Now I'm sure that some of the loaded modules will not be used at least
for a long time. How can I unload them?

Yes, code:delete/1 and code:purge/1. If you know nobody uses tha code,
the latter will also clean up the memory.

Thank you. I searched for "unload" but there is "remove" in docs.
