NEWS
geigen 2.3 (2019-05-30)
- removed various Lapack routines that are now included in the R Lapack sources.
- changed dependency on the version of R (>= 3.5.0)
geigen 2.2 (2018-05-17)
- changed package documentation .Rd to update metadata
- updated lapack routines to version 3.8.0; many Fortran routines unchanged from Lapack 3.7.0.
Changes are minimal.
geigen 2.1 (2017-08-22)
- clarification in documentation of geigen about when the second matrix must be positive definite.
- corrected documentation of gqz; matrices need not be positive definite.
geigen 2.0 (2017-02-16)
- register native routines in dll
- added NeedsCompilation field to DESCRIPTION
- use subroutines from Lapack 3.7.0 (no differences in actual code)
geigen 1.9.2 (2016-09-05)
- in all files src/x*.f obsolescent Fortran character* declarations replaced
- in all files src/x*.f use <double complex> instead of <complex*16> but
Lapack routines using <complex*16> have not been changed
geigen 1.9.1 (2016-08-07)
- moved zheg* routines to separate file
- updated Lapack routines to version 3.6.1
- documentation tweaks
geigen 1.9 (2016-01-07)
- update to routines from Lapack 3.6.0 and use new gsvd routines
- Lapack zzgsvd3 and zzgsvp3 from svn revision 1664 and 1671
geigen 1.8 (2015-11-02)
- gsvd now also handles complex matrices
geigen 1.7 (2015-10-15)
- documentation tweaks
- gsvd does not handle complex matrices
- removed CITATION and let it be auto generated (to get details correct)
geigen 1.6 (2015-07-16)
- added a Generalized Singular Value Decomposition of a matrix pair
- documentation tweaks
geigen 1.5 (2015-02-12)
- change to titlecase in several places and update CITATION
- additional comments in cmplxdiv.R about weird complex division on some systems
geigen 1.4 (2014-08-18)
- replaced zgetc2 in zggesall.f with Lapack 3.5.0 version
- additional tests
- fix some ftnchek warning/error messages
geigen 1.3 (2013-08-27)
- added function for computing generalized eigenvalues from a generalized Schur decomposition
- introduced S3 classes and methods for calculating generalized
eigenvalues from the generalized Schur decomposition
- added Copyright field in DESCRIPTION
- documentation tweaks and clarifications
geigen 1.2 (2013-06-18)
- added Lapack Licence
- added alpha and beta to return list of geigen() and gqz() for safe calculation of generalized eigenvalues
- improved sorting eigenvalues for singular matrix B
- improved calculation of eigenvalues for singular B matrix in geigen()
- detailed Lapack error/informative messages
- option 'R' in gqz() didn't function correctly.
Corrected errors and now uses a tolerance for testing zero imaginary part.
geigen 1.1 (2013-05-23)
- corrected error message in gqz()
- stricter test of sorting for gqz()
- 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
- renamed src/xdgg.f to src/xdggev.f
