- Removed deprecated stuff from Build.PL and added Module::Build to configure_requires
- Many small documentation improvements
- Fix build on Windows - Sisyphus
=head1 v0.25 - April 2011
- TODO RT#66882 properly so that a stable release with a passing test suite can be used.
=head1 v0.24 - April 2011
- Fix https://rt.cpan.org/Ticket/Display.html?id=66882 (Tests fail on Perl's with DUSELONGDOUBLE)
=head1 v0.23 - March 2011
- Fixed the tolerance of some tests that were causing CPANtesters failures
- Fixed some doc typos
=head1 v0.22 - June 2010
- Improved tests
- == and != operators for Vectors
- Fixed the export of hypergeometric functions (Thierry Moisan)
- In instantiation of GSLBuilder in Build.PL, the value for the parameter
include_dirs were corrected to an anonymous empty array, instead of an
empty string. (Jakob Ilves)
- Operator overloading of vector equality (Thierry Moisan)
- Various doc fixes (Pjotr Prins)
- Typemap fixes (Vincent Danjean)
=head1 v0.20 - May 19 2009
- $rng->get($n) will now return the next $n values of the random number generator
- Fixed + added test for RT#45044 math-gsl eigenpair bug, reported with patch by Ian Malone
- Added more tests for Randist
- Fixed some incorrectly written tests for BLAS and Linalg
- Improved NTuple support and tests
- Improvements to callbacks, thanks to patches from piotrj
- The following improvements were merged from Vincent Danjean's git repo:
- Fixed some memory leaks caused by in-typemaps without argout-typemaps
- Improved portable callback implementation
- Correct handling of double, float and size_t on x64
- Removed duplicate definition of fopen/fclose in VectorComplex
- Fix bug where proper flags to SWIG were not passed
=head1 v0.18 - March 23 2009
- Make Math::GSL play nice with GSL 1.12
- Added swap() to Vector objects with tests and docs
- Added p-norms to Vector objects via norm() and normalize()
- Added operator overloading so that
abs $vector == $vector->norm
- Added as_vector() to Matrix and MatrixComplex objects
- Added inverse(), is_square(), det(), lndet(), zero() and identity()
to Matrix objects
- Added inverse(), is_square(), det(), lndet(), zero(), identity()
and hermitian() to MatrixComplex objects
- Added dot product to Matrix objects
- Fixed various typos in documentation
- Fixed warnings about overloaded operators in Matrix and BLAS
- Overloaded '==' and '!=' for MatrixComplex and Matrix objects
- Fixed amd64 -fPIC compile failure
- Added tests to Monte and refactor Sort tests
- Refactored and improve error checking in callback interface
- Fixed 'NaN' test failures (thanks CPANtesters!)
=head1 v0.16 - December 14 2008 (Happy Snowpocalypse PDX!)
- Fixed RT#40947: configure_requires ExtUtils::PkgConfig bug
- Added reverse() and swap() methods to VectorComplex objects with tests and docs
- as_list() and get() now work on VectorComplex objects
as_list() returns a list of Math::Complex objects
get() returns a list of Math::GSL::Complex objects
- Math::GSL::Test::ok_status() now takes an optional message argument
- Added KNOWN_BUGS
- Added Math::GSL::Test::is_status_ok()
- New subsytems: VectorComplex and MatrixComplex
- Operator overloading for addition and subtraction with vectors
- Added example: examples/matrix/nonsymmetric_eigen
Shows how to find the eigenvalues of a nonsymmetric matrix
- Added copy() method to vectors
- Improved Vector docs
- Sped up vector dot products by 15x using BLAS function gsl_blas_ddot
NOTE: using gsl_blas_ddot($x->raw,$y->raw) directly is still about 10 times faster
than $x * $y due to error checking and function call overhead
- Separated POD and Perl code out of SWIG interface files, yay for proper syntax
highlighting
- Added stub test files for Heapsort, IEEEUtils, Multimin, Siman, Wavelet2D
- All test files now keep track of how many tests should run
- Fix an include bug in Histogram2D which caused the build to fail (Thierry)
- Operator overloading for addition, multiplication and subtraction on Matrix objects (Thierry)
=head1 v0.14 - October 21 2008
- Chebyshev Series Approximation, with tests and docs
- Examples and new documentation in Statistics, as well as tests (Thierry)
- Bugfixes relating to compiling on 64bit Red Hat Linux, reported by Michael Roberge
- Improved FFT, Deriv, Integration, Chebyshev, Combination and Roots docs
- Documentation for Math::GSL::Test
- Improved introduction examples in Math::GSL
- Improved Minimization subsystem tests, but it is not functional
- Added examples/fft/forward_real
- Added example/deriv/basic
This shows the simple fact that d/dx(sin(x)) = cos(x)
- Added example/sf/erfc_check (thanks to Keith Lofstrom)
Script which tests the erfc() special function against computing
the integral definition with gsl_integration_qagiu()
- Added example/vector/speed
This shows a considerable performance boost using Math::GSL::Vectors
instead of List::Util when searching for the min and max elements of
large sets of random numbers.
- Fixed return signature of gsl_deriv_* functions to return a flat list
- Fixed some failing tests relating to -Duselongdouble (Sisyphus)
