  "Description": "Generalized eigenvalues and eigenvectors use QZ\ndecomposition (generalized Schur decomposition). The\ndecomposition needs an N-by-N non-symmetric matrix A or paired\nmatrices (A,B) with eigenvalues reordering mechanism. The\ndecomposition functions are mainly based Fortran subroutines in\ncomplex*16 and double precision of LAPACK library (version\n3.10.0 or later).",
