2004-12-03  Brian Gough  <bjg@network-theory.co.uk>

	* jacobi.c (gsl_eigen_jacobi): use algorithm from Golub and Van
	Loan
	(gsl_eigen_invert_jacobi): new code

2003-01-02  Brian Gough  <brian.gough@network-theory.co.uk>

	* symmv.c (gsl_eigen_symmv): change gsl_isnan to isnan

	* symm.c (gsl_eigen_symm): change gsl_isnan to isnan

	* hermv.c (gsl_eigen_hermv): change gsl_isnan to isnan

	* herm.c (gsl_eigen_herm): change gsl_isnan to isnan

2002-11-16  Brian Gough  <bjg@network-theory.co.uk>

	* symm.c (gsl_eigen_symm): prevent infinite loop for NaNs

	* herm.c (gsl_eigen_herm): prevent infinite loop for NaNs

	* symmv.c (gsl_eigen_symmv): prevent infinite loop for NaNs

	* hermv.c (gsl_eigen_hermv): prevent infinite loop for NaNs

Fri Oct 18 17:58:35 2002  Brian Gough  <bjg@network-theory.co.uk>

	* test.c (main): added test cases to catch division by zero
 	(beta_r=0) in householdercomplex.c

Wed Aug 28 19:05:54 2002  Brian Gough  <bjg@network-theory.co.uk>

	* Makefile.am (test_LDADD): fix link order to have libgslsys near
 	end

Thu Aug  2 18:17:58 2001  Brian Gough  <bjg@network-theory.co.uk>

	* hermv.c (gsl_eigen_hermv): fixed index bug in accumulation of evec.

	* symmv.c (gsl_eigen_symmv): fixed index bug in accumulation of evec.

	* test.c (main): added two new test cases

	* qrstep.c (trailing_eigenvalue): chose better value of mu when
 	dt=0, prevents infinite loop.

Sun Jul  1 22:43:45 2001  Brian Gough  <bjg@network-theory.co.uk>

	*  modified to use new-style vector views

Wed Jun 20 12:30:38 2001  Brian Gough  <bjg@network-theory.co.uk>

	* hermv.c (gsl_eigen_hermv): additional workspace argument no
 	longer required

Mon Apr 23 10:31:01 2001  Brian Gough  <bjg@network-theory.co.uk>

	* unified error handling conventions to _e for error handling
 	functions and no suffix for plain functions, so _impl functions
 	are no longer needed.

	* removed tests for EFAULT, since EFAULT should only apply to
 	invalid non-null pointers.
	
Fri Apr 13 20:33:18 2001  Brian Gough  <bjg@network-theory.co.uk>

	* eigen/test.c (test_invert_jacobi): removed matmult and replaced
 	by gsl_blas_dgemm
