The computation of eigenvalues can be used for the determinant, or perhaps there is a more specific LAPACK function

When I get the `FaceGeometricFactors` for 2-D boundaries in 3-D space, the Jacobian matrix is empty. The code is
```
if (dim == 2)
const FaceGeometricFactors *face_geom = mesh->GetFaceGeometricF…

1) Are we allowed to use functions that give determinant and inverse of a 3x3 matrix or are we supposed to manually compute one/both of them
2) Also if these functions work without including Eigen/…

Hi everyone!
Thank you very much for your package, it is great to have a Python quantum chemistry tool!!
However, I can't quite wrap my head around the following problem: suppose I have a mean-fie…

I've been locally testing my Jacobian derivations in Julia with AD, but ideally our Stan implementations would be tested for correctness as well by computing the Jacobian of the actual transforms usin…

Dear sir,
I have discovered a small bug in the matrix determinant function. It appears that the function does not account for 1x1 matrices, and instead causes a segmentation fault, despite the defau…
