Generalized Eigenvalues and QZ Decomposition R package QZ version 0.2-4 CRAN Task View: NumericalMathematics (https://CRAN.R-project.org/view=NumericalMathematics) Generalized eigenvalues and eigenvectors use QZ decomposition (generalized Schur decomposition). The decomposition needs an N-by-N non-symmetric matrix A or paired matrices (A,B) with eigenvalues reordering mechanism. The decomposition functions are mainly based Fortran subroutines in complex*16 and double precision of LAPACK library (version 3.10.0 or later).
