[gmx-developers] use of f[] in do_shakefirst

[D. Ensign]

Greetings,

I was wondering, what's the reason for using f[] for what looks like a temporary storage
spot in do_shakefirst()? Would I lose performance if I had a special rvec in
do_shakefirst() for this purpose, instead of using f[]? The reason I ask is, with my
modifications f[] is now a special type, not rvec, and not necessarily the same precision
as rvec.
