Software Availability

The software package (in FORTRAN 77) for computing a GUPTRI form of an arbitrary $A - \lambda B$ and error bounds for computed generalized eigenvalues and reducing subspaces was published in [121,122]. The software is developed for dense matrices stored as double precision complex data. An interface to MATLAB in terms of a MEX-file is also available. See the book's homepage, ETHOME, for access to this software.
