** Generalized eigenvalues. **

** [AA, BB, Q, Z, V] = QZ(A,B) for square matrices A and B, **

** produces upper triangular matrices AA and BB, matrices Q **

** and Z containing the products of the left and right trans- **

** formations, such that Q*A*Z = AA, and Q*B*Z = BB, and the **

** generalized eigenvector matrix V. **

** The alphas and betas comprising the generalized eigenvalues **

** are the diagonal elements of AA and BB so that **

** A*V*diag(BB) = B*V*diag(AA). **
