Inverse and Determinant
- CPU version uses Eigen
- GPU version uses LAPACK-compatible getrf / getri
Design comment: Eigen does not expose getrf / getri in a LAPACK compatible manner.
Overhead to go through getrf / getri for CPU version too large.
Current interface therefore only guarantees the inverse and determinant
functions on all platforms but not the getrf / getri ones.
