use references

[jacobmerson]

Your current code is making full copies of those vectors you should instead just get a const-reference to the array.

STOMMS/src/modeling.cc

Lines 24 to 30 in 8878501

	std::vector <double> R = vm.R;
	std::vector <double> Z = vm.Z;
	std::vector <double> L = vm.L;
	std::vector <double> iota = vm.iota;
	std::vector <double> psi = vm.psi;
	std::vector <double> xm = vm.xm;
	std::vector <double> xn = vm.xn;

For example, you can do:

const std::vector <double>& xn = vm.xn; or better const auto& xn = vm.xn;
