1 =head1 Math::GSL Changes
3 =head1 v0.20 - May 19 2009

6 - Added more tests for Randist
7 - Fixed some incorrectly written tests for BLAS and Linalg
8 - Improved NTuple support and tests

10 - The following improvements were merged from Vincent Danjean's git repo:
11 - Fixed some memory leaks caused by in-typemaps without argout-typemaps
12 - Improved portable callback implementation
13 - Correct handling of double, float and size_t on x64
14 - Removed duplicate definition of fopen/fclose in VectorComplex
15 - Fix bug where proper flags to SWIG were not passed
17 =head1 v0.18 - March 23 2009
19 - Make Math::GSL play nice with GSL 1.12
20 - Added swap() to Vector objects with tests and docs
21 - Added p-norms to Vector objects via norm() and normalize()
22 - Added operator overloading so that
23 abs $vector == $vector->norm
24 - Added as_vector() to Matrix and MatrixComplex objects
25 - Added inverse(), is_square(), det(), lndet(), zero() and identity()
27 - Added inverse(), is_square(), det(), lndet(), zero(), identity()
28 and hermitian() to MatrixComplex objects
29 - Added dot product to Matrix objects
30 - Fixed various typos in documentation
31 - Fixed warnings about overloaded operators in Matrix and BLAS
32 - Overloaded '==' and '!=' for MatrixComplex and Matrix objects
33 - Fixed amd64 -fPIC compile failure
34 - Added tests to Monte and refactor Sort tests
35 - Refactored and improve error checking in callback interface
36 - Fixed 'NaN' test failures (thanks CPANtesters!)
38 =head1 v0.16 - December 14 2008 (Happy Snowpocalypse PDX!)
40 - Fixed RT#40947: configure_requires ExtUtils::PkgConfig bug
41 - Added reverse() and swap() methods to VectorComplex objects with tests and docs
42 - as_list() and get() now work on VectorComplex objects
43 as_list() returns a list of Math::Complex objects
44 get() returns a list of Math::GSL::Complex objects
45 - Math::GSL::Test::ok_status() now takes an optional message argument
47 - Added Math::GSL::Test::is_status_ok()
48 - New subsytems: VectorComplex and MatrixComplex
49 - Operator overloading for addition and subtraction with vectors
50 - Added example: examples/matrix/nonsymmetric_eigen
51 Shows how to find the eigenvalues of a nonsymmetric matrix
52 - Added copy() method to vectors
53 - Improved Vector docs
54 - Sped up vector dot products by 15x using BLAS function gsl_blas_ddot
55 NOTE: using gsl_blas_ddot($x->raw,$y->raw) directly is still about 10 times faster
56 than $x * $y due to error checking and function call overhead
57 - Separated POD and Perl code out of SWIG interface files, yay for proper syntax
59 - Added stub test files for Heapsort, IEEEUtils, Multimin, Siman, Wavelet2D
60 - All test files now keep track of how many tests should run
61 - Fix an include bug in Histogram2D which caused the build to fail (Thierry)
62 - Operator overloading for addition, multiplication and subtraction on Matrix objects (Thierry)
65 =head1 v0.14 - October 21 2008
67 - Chebyshev Series Approximation, with tests and docs
68 - Examples and new documentation in Statistics, as well as tests (Thierry)
69 - Bugfixes relating to compiling on 64bit Red Hat Linux, reported by Michael Roberge
70 - Improved FFT, Deriv, Integration, Chebyshev, Combination and Roots docs
71 - Documentation for Math::GSL::Test
72 - Improved introduction examples in Math::GSL
73 - Improved Minimization subsystem tests, but it is not functional
74 - Added examples/fft/forward_real
75 - Added example/deriv/basic
77 This shows the simple fact that d/dx(sin(x)) = cos(x)
79 - Added example/sf/erfc_check (thanks to Keith Lofstrom)
81 Script which tests the erfc() special function against computing
82 the integral definition with gsl_integration_qagiu()
84 - Added example/vector/speed
86 This shows a considerable performance boost using Math::GSL::Vectors
87 instead of List::Util when searching for the min and max elements of
88 large sets of random numbers.
90 - Fixed return signature of gsl_deriv_* functions to return a flat list
91 - Fixed some failing tests relating to -Duselongdouble (Sisyphus)
92 - Fix location of shared objects (Sisyphus)
93 - Added raw() method to RNG objects
95 =head1 v0.12 - September 14 2008
98 - Minimum Perl version changed to 5.8.0
99 - Make platform check compile time constants for performance
100 aka The Wilhelm Speedup (thanks to Eric Wilhelm <scratchcomputing@gmail.com>)
102 - Numerical derivatives fully implemented
103 - Integration subsystem, gsl_integrate_qags() and gsl_integrate_qagi(), etc..
104 - QNG : Non-adaptive Gaussian (uses fixed number of sample points in interval)
105 - QAG(S) : Adaptive Gaussian (Singluar) (slices interval up based on properties of the function)
106 - QAGI : Adaptive Gaussian with infinite integration range
107 - other are supported but not tested
108 - Initial Monte tests
109 - Initial Multiroots tests
110 - More nan/inf fixes on MSWin32 from <sisyphus@cpan.org>

112 from <sisyphus@cpan.org>
113 - Full support and tests for all functions in the Sort subsystem
114 - Added 'examples/benchmark/sort' to show performance of gsl_sort()
115 - Added 'examples/clicker/chart' to show graphing of functions
116 - Added 'examples/gsl_repl' which is a rapid protyping tool/interactive interpreter
117 - Compile support for GSL's as old as 1.8 (test suite still needs to be properly guarded)
121 - Continued porting to MSWin32, fixing many NaN and Inf handling issues
125 - Large documentation improvements
126 - MSWin32 support thanks to testing and feedback from <sisyphus@cpan.org>
130 - Initial CPAN release
134 - Started change to Test::Class
138 - Added swig interface files and swig-ified build script
139 - initial tests for special function library gsl_sf <--> Math::GSL::Sf
