2.1
o clarification in documentation of geigen about when the second matrix must be positive definite.
o corrected documentation of gqz; matrices need not be positive definite.
2.0
o register native routines in dll
o added NeedsCompilation field to DESCRIPTION
o use subroutines from Lapack 3.7.0 (no differences in actual code)
1.9.2
o in all files src/x*.f obsolescent Fortran character* declarations replaced
o in all files src/x*.f use instead of but
Lapack routines using have not been changed
1.9.1
o moved zheg* routines to separate file
o updated Lapack routines to version 3.6.1
o documentation tweaks
1.9
o update to routines from Lapack 3.6.0 and use new gsvd routines
o Lapack zzgsvd3 and zzgsvp3 from svn revision 1664 and 1671
1.8
o gsvd now also handles complex matrices
1.7
o documentation tweaks
o gsvd does not handle complex matrices
o removed CITATION and let it be auto generated (to get details correct)
1.6
o added a Generalized Singular Value Decomposition of a matrix pair
o documentation tweaks
1.5
o change to titlecase in several places and update CITATION
o additional comments in cmplxdiv.R about weird complex division on some systems
1.4
o replaced zgetc2 in zggesall.f with Lapack 3.5.0 version
o additional tests
o fix some ftnchek warning/error messages
1.3
o added function for computing generalized eigenvalues from a generalized Schur decomposition
o introduced S3 classes and methods for calculating generalized
eigenvalues from the generalized Schur decomposition
o added Copyright field in DESCRIPTION
o documentation tweaks and clarifications
1.2
o added Lapack Licence
o added alpha and beta to return list of geigen() and gqz() for safe calculation of generalized eigenvalues
o improved sorting eigenvalues for singular matrix B
o improved calculation of eigenvalues for singular B matrix in geigen()
o detailed Lapack error/informative messages
o option 'R' in gqz() didn't function correctly.
Corrected errors and now uses a tolerance for testing zero imaginary part.
1.1
o corrected error message in gqz()
o stricter test of sorting for gqz()
o modified all intermediate Fortran subroutines to have integer arguments
which are transferred to character*1 variables for calling the actual Lapack subroutines
since on some platforms the Fortran runtime did not accept character in routines called by R
o renamed src/xdgg.f to src/xdggev.f
1.0
o initial version
