1 =head1 Math::GSL Changes
3 =head1 v0.19_02 - April 2008
4 - Improvements to callbacks, thanks to patches from piotrj
5 - Fixed + added test for RT#45044 math-gsl eigenpair bug, reported with patch by Ian Malone
6 - The following improvements were merged from Vincent Danjean's git repo
7 - New callback implementation, still in testing
8 - Correct handling of double, float and size_t on x64
9 - Removed duplicate definition of fopen/fclose in VectorComplex
11 =head1 v0.18 - March 23 2008
13 - Make Math::GSL play nice with GSL 1.12
14 - Added swap() to Vector objects with tests and docs
15 - Added p-norms to Vector objects via norm() and normalize()
16 - Added operator overloading so that
17 abs $vector == $vector->norm
18 - Added as_vector() to Matrix and MatrixComplex objects
19 - Added inverse(), is_square(), det(), lndet(), zero() and identity()
21 - Added inverse(), is_square(), det(), lndet(), zero(), identity()
22 and hermitian() to MatrixComplex objects
23 - Added dot product to Matrix objects
24 - Fixed various typos in documentation
25 - Fixed warnings about overloaded operators in Matrix and BLAS
26 - Overloaded '==' and '!=' for MatrixComplex and Matrix objects
27 - Fixed amd64 -fPIC compile failure
28 - Added tests to Monte and refactor Sort tests
29 - Refactored and improve error checking in callback interface
30 - Fixed 'NaN' test failures (thanks CPANtesters!)
32 =head1 v0.16 - December 14 2008 (Happy Snowpocalypse PDX!)
34 - Fixed RT#40947: configure_requires ExtUtils::PkgConfig bug
35 - Added reverse() and swap() methods to VectorComplex objects with tests and docs
36 - as_list() and get() now work on VectorComplex objects
37 as_list() returns a list of Math::Complex objects
38 get() returns a list of Math::GSL::Complex objects
39 - Math::GSL::Test::ok_status() now takes an optional message argument
41 - Added Math::GSL::Test::is_status_ok()
42 - New subsytems: VectorComplex and MatrixComplex
43 - Operator overloading for addition and subtraction with vectors
44 - Added example: examples/matrix/nonsymmetric_eigen
45 Shows how to find the eigenvalues of a nonsymmetric matrix
46 - Added copy() method to vectors
47 - Improved Vector docs
48 - Sped up vector dot products by 15x using BLAS function gsl_blas_ddot
49 NOTE: using gsl_blas_ddot($x->raw,$y->raw) directly is still about 10 times faster
50 than $x * $y due to error checking and function call overhead
51 - Separated POD and Perl code out of SWIG interface files, yay for proper syntax
53 - Added stub test files for Heapsort, IEEEUtils, Multimin, Siman, Wavelet2D
54 - All test files now keep track of how many tests should run
55 - Fix an include bug in Histogram2D which caused the build to fail (Thierry)
56 - Operator overloading for addition, multiplication and subtraction on Matrix objects (Thierry)
59 =head1 v0.14 - October 21 2008
61 - Chebyshev Series Approximation, with tests and docs
62 - Examples and new documentation in Statistics, as well as tests (Thierry)
63 - Bugfixes relating to compiling on 64bit Red Hat Linux, reported by Michael Roberge
64 - Improved FFT, Deriv, Integration, Chebyshev, Combination and Roots docs
65 - Documentation for Math::GSL::Test
66 - Improved introduction examples in Math::GSL
67 - Improved Minimization subsystem tests, but it is not functional
68 - Added examples/fft/forward_real
69 - Added example/deriv/basic
71 This shows the simple fact that d/dx(sin(x)) = cos(x)
73 - Added example/sf/erfc_check (thanks to Keith Lofstrom)
75 Script which tests the erfc() special function against computing
76 the integral definition with gsl_integration_qagiu()
78 - Added example/vector/speed
80 This shows a considerable performance boost using Math::GSL::Vectors
81 instead of List::Util when searching for the min and max elements of
82 large sets of random numbers.
84 - Fixed return signature of gsl_deriv_* functions to return a flat list
85 - Fixed some failing tests relating to -Duselongdouble (Sisyphus)
86 - Fix location of shared objects (Sisyphus)
87 - Added raw() method to RNG objects
89 =head1 v0.12 - September 14 2008
92 - Minimum Perl version changed to 5.8.0
93 - Make platform check compile time constants for performance
94 aka The Wilhelm Speedup (thanks to Eric Wilhelm <scratchcomputing@gmail.com>)
96 - Numerical derivatives fully implemented
97 - Integration subsystem, gsl_integrate_qags() and gsl_integrate_qagi(), etc..
98 - QNG : Non-adaptive Gaussian (uses fixed number of sample points in interval)
99 - QAG(S) : Adaptive Gaussian (Singluar) (slices interval up based on properties of the function)
100 - QAGI : Adaptive Gaussian with infinite integration range
101 - other are supported but not tested
102 - Initial Monte tests
103 - Initial Multiroots tests
104 - More nan/inf fixes on MSWin32 from <sisyphus@cpan.org>
105 - Stripping of binaries on Windows, which significantly reduces size
106 from <sisyphus@cpan.org>
107 - Full support and tests for all functions in the Sort subsystem
108 - Added 'examples/benchmark/sort' to show performance of gsl_sort()
109 - Added 'examples/clicker/chart' to show graphing of functions
110 - Added 'examples/gsl_repl' which is a rapid protyping tool/interactive interpreter
111 - Compile support for GSL's as old as 1.8 (test suite still needs to be properly guarded)
115 - Continued porting to MSWin32, fixing many NaN and Inf handling issues
119 - Large documentation improvements
120 - MSWin32 support thanks to testing and feedback from <sisyphus@cpan.org>
124 - Initial CPAN release
128 - Started change to Test::Class
132 - Added swig interface files and swig-ified build script
133 - initial tests for special function library gsl_sf <--> Math::GSL::Sf
134 - Proof Of Concept: makegsl and testgsl
