Milestone: 9.19.0

What is new in gsl-2.6:

  • add BLAS calls for the following functions:
    • gsl_vector_memcpy
    • gsl_vector_scale
    • gsl_matrix_memcpy
    • gsl_matrix_transpose_memcpy
    • gsl_matrix_tricpy
    • gsl_matrix_transpose_tricpy
  • deprecated functions gsl_linalg_complex_householder_hm and gsl_linalg_complex_householder_mh
  • add unit tests for gsl_linalg_symmtd and gsl_linalg_hermtd
  • multilarge TSQR algorithm has been converted to use the new Level 3 QR decomposition

  • nonlinear least squares Cholesky solver now uses the new Level 3 BLAS method; the old modified Cholesky solver is still available under gsl_multifit_nlinear_solver_mcholesky and gsl_multilarge_nlinear_solver_mcholesky
  • implemented Level 3 BLAS versions of several linear algebra routines:
    • Triangular matrix inversion
    • Cholesky decomposition and inversion (real and complex)
    • LU decomposition and inversion (real and complex)
    • QR decomposition (courtesy of Julien Langou)
    • Generalized symmetric/hermitian eigensystem reduction to standard form
  • removed deprecated function gsl_linalg_hessenberg()
  • renamed gsl_interp2d_eval_e_extrap() to gsl_interp2d_eval_extrap_e() to match documentation (reported by D. Lebrun-Grandie)
  • renamed some of the gsl_sf_hermite functions to be more consistent with rest of the library, and deprecated old function names
  • updated gsl_sf_hermite_func() to use a newer algorithm due to B. Bunck which is more stable for large x; also added gsl_sf_hermite_func_fast() which uses the faster Cauchy integral algorithm in the same paper by Bunck
  • add gsl_vector_axpby()
  • add un-pivoted LDLT decomposition and its banded variant (gsl_linalg_ldlt_* and gsl_linalg_ldlt_band_*)
  • add binary search tree module (gsl_bst); based on GNU libavl
  • remove -u flag to gsl-histogram
  • updated spmatrix module
    • added routines and data structures for all types (float,uint,char,...)
    • added gsl_spmatrix_scale_columns() and gsl_spmatrix_scale_rows()
    • added gsl_spmatrix_add_to_dense()
    • more efficient reallocation of COO/triplet matrices (no longer rebuilds binary tree)
    • enhanced test suite
    • added gsl_spmatrix_min_index()
  • add routines for banded Cholesky decomposition (gsl_linalg_cholesky_band_*)
  • documented gsl_linalg_LQ routines and added gsl_linalg_LQ_lssolve()

I forgot to bump the version number last night. Sorry about that!
