Is there anywhere an introductory piece on the difference between an array and a vector?
it seems to me that if I tried to use
real variable[N];, it just raises syntactic error down the road.
For example, if I change the model in recent StanCon Helsinki 2018 tutorial link line 16 from vector to real, I got:
No matches for: real * real
The real question here is when should I use real[N]; instead of vector?
