Detailed Description

Squared error metric for computing \(L^2\) error of Ringleb flow.

Computes the squared difference between the given position vector and what the position vector should be based on the state if the state were an exact solution. Computing the error in the state vector based on the position would be nicer, but that's actually kind of hard because it involves numerically finding roots of a somewhat ill-behaved function.
