Hello.

Let's say that I have a code which including for loop. In the loop, certain function is called at every round. How can I make it stay in the memory so code doesn't need to call it every time?

The function is complicated thus anonymous function is not suitable.

The first time you call a function it is parsed and put into memory. It will subsequently stay in memory unless you do something to clear it out of memory. You don't need to do anything special to get this to happen. E.g., see this:
