Hi, I'm working on a code where essentially I have two very large arrays q and b and I have this function Hamiltonian(double * v1, double * v2) which takes the points of two arrays and does all sorts of things with them. Anyways. If I write my code using Hamiltonian(q,b) my code runs FASTER than if I just copy and paste everything that was in the function Hamiltonian and just plunk it in my main statement. Why should this be? Doesn't the compiler just put it in line anyways when it is compiling to assembly?
