Functionality
|
This package of routines contains robust software with error bounds for computing the generalized Schur decomposition of an arbitrary pencil A - zB (regular or singular). The decomposition (GUPTRI - Generalized Upper TRIangular form) is a generalization of the Schur canonical form of A - zI to matrix pencils and reveals the Kronecker structure of a singular pencil.
