\section{Scaled Jacobian}

This metric is the minimum determinant of the Jacobian matrix
evaluated at each corner and the center of the element,
divided by the corresponding edge lengths.
\[
q = \min_{i\in\{0,1,\ldots,8\}}\left\{\hat\alpha_i\right\}.
\]

Note that if ${L_{\min}}^2 \leq DBL\_MIN$, we set $q = DBL\_MAX$.
