On Apple MPS (:mps), LU, Eigh, Solve, Determinant and Cholesky fall back to
Nx (slower). QR, SVD and triangular solve run on the CPU and copy the results
back.
Nx.LinAlg.solve/2
Singular matrices raise ArgumentError with "can't solve for singular matrix".
Nx.LinAlg.qr/2
:eps is ignored.
Nx.LinAlg.eigh/2
:max_iter and :eps are ignored, except on MPS where Nx's implementation is
used.
Nx.LinAlg.svd/2
Complex inputs raise. :max_iter is ignored.
Nx.LinAlg.triangular_solve/3
left_side: false raises. Singular matrices raise the same error as solve/2.
