The third step of the QZ algorithm for generalized eigenproblems. Accepts a pair of real matrices, one in quasi-triangular form and the other in upper triangular form and computes the eigenvalues of the associated eigenproblem. Usually preceded by QZHES, QZIT, and followed by QZVEC. Classes : D4c2c . Compute eigenvalues of matrices in other compact forms Type : Fortran subroutine in CMLIB library (EISPACK sublibrary). Access : Public domain. Portable. Precision: Single. Usage : CALL QZVAL(NM,N,A,B,ALFR,ALFI,BETA,MATZ,Z) See also : QZHES QZIT QZVEC Details : Documentation Fullsource Source Sites : (1) ARNO (2) ITL
