* Added a new wavelet directory, with 1-dimensional and 2-dimensional
discrete wavelet transforms.
* Added support for LQ and P^T LQ decompositions. To find the QR
decomposition of large systems (M>>N) use the LQ decomposition,
solving the transpose of the original system. This allows more
efficient memory access, and is useful for solving large least-squares
problems.
* Fixed a bug in the SYRK and HERK blas functions gsl_blas_{s,d,c,z}syrk
and gsl_blas_{c,z}herk which caused invalid memory access for non-square
matrices.
* Fixed a bug in gsl_swap_vectors which caused it to return incorrect
results when swapping vectors with different strides.
* Corrected the error estimate for gsl_cheb_eval_n_err to use
evaluation order instead of the approximation order.
* Improved the reliability of the gsl_sf_gamma_inc family of
functions.
* Equal abscissae are now handled gracefully in the cspline and
periodic cspline interpolations.
* Removed potential cancellation error in calculation of uniform
histogram ranges.
* Improved numerical stability of integration for akima and cspline
interpolation.
* Differential equation solvers now handle error codes returned from
user-defined functions.
* Improved error estimates in ode-initval solvers, and provide exact
derivatives on output. Added new semi-implicit ode-initval solver,
gsl_odeiv_step_rk2simp.
* Added missing function definition for gsl_sf_psi_1.
* Fixed the function gsl_sf_expint_Ei_scaled to call
gsl_sf_expint_Ei_scaled_e instead of gsl_sf_expint_Ei_e.
* Added cumulative distribution function for exponential power
distribution.
* The functions gsl_cdf_beta_P and gsl_cdf_beta_Q now return
consistent results of 0 or 1 for out of range values, x<0 and x>1,
rather than 0 for left and right tails simultaneously.
* The Jacobi eigensolvers gsl_eigen_jacobi and gsl_eigen_jacobi_invert
have new implementations from Golub and Van Loan.
* The standard output and standard error streams are now flushed by
the default error handler before the program aborts, in order to
ensure that error messages are properly displayed on some platforms.
