1 =head1 Math::GSL Changes
3 =head1 v0.20 - 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
7 =head1 v0.18 - March 23 2008
9 - Make Math::GSL play nice with GSL 1.12
10 - Added swap() to Vector objects with tests and docs
11 - Added p-norms to Vector objects via norm() and normalize()
12 - Added operator overloading so that
13 abs $vector == $vector->norm
14 - Added as_vector() to Matrix and MatrixComplex objects
15 - Added inverse(), is_square(), det(), lndet(), zero() and identity()
17 - Added inverse(), is_square(), det(), lndet(), zero(), identity()
18 and hermitian() to MatrixComplex objects
19 - Added dot product to Matrix objects
20 - Fixed various typos in documentation
21 - Fixed warnings about overloaded operators in Matrix and BLAS
22 - Overloaded '==' and '!=' for MatrixComplex and Matrix objects
23 - Fixed amd64 -fPIC compile failure
24 - Added tests to Monte and refactor Sort tests
25 - Refactored and improve error checking in callback interface
26 - Fixed 'NaN' test failures (thanks CPANtesters!)
28 =head1 v0.16 - December 14 2008 (Happy Snowpocalypse PDX!)
30 - Fixed RT#40947: configure_requires ExtUtils::PkgConfig bug
31 - Added reverse() and swap() methods to VectorComplex objects with tests and docs
32 - as_list() and get() now work on VectorComplex objects
33 as_list() returns a list of Math::Complex objects
34 get() returns a list of Math::GSL::Complex objects
35 - Math::GSL::Test::ok_status() now takes an optional message argument
37 - Added Math::GSL::Test::is_status_ok()
38 - New subsytems: VectorComplex and MatrixComplex
39 - Operator overloading for addition and subtraction with vectors
40 - Added example: examples/matrix/nonsymmetric_eigen
41 Shows how to find the eigenvalues of a nonsymmetric matrix
42 - Added copy() method to vectors
43 - Improved Vector docs
44 - Sped up vector dot products by 15x using BLAS function gsl_blas_ddot
45 NOTE: using gsl_blas_ddot($x->raw,$y->raw) directly is still about 10 times faster
46 than $x * $y due to error checking and function call overhead
47 - Separated POD and Perl code out of SWIG interface files, yay for proper syntax
49 - Added stub test files for Heapsort, IEEEUtils, Multimin, Siman, Wavelet2D
50 - All test files now keep track of how many tests should run
51 - Fix an include bug in Histogram2D which caused the build to fail (Thierry)
52 - Operator overloading for addition, multiplication and subtraction on Matrix objects (Thierry)
55 =head1 v0.14 - October 21 2008
57 - Chebyshev Series Approximation, with tests and docs
58 - Examples and new documentation in Statistics, as well as tests (Thierry)
59 - Bugfixes relating to compiling on 64bit Red Hat Linux, reported by Michael Roberge
60 - Improved FFT, Deriv, Integration, Chebyshev, Combination and Roots docs
61 - Documentation for Math::GSL::Test
62 - Improved introduction examples in Math::GSL
63 - Improved Minimization subsystem tests, but it is not functional
64 - Added examples/fft/forward_real
65 - Added example/deriv/basic
67 This shows the simple fact that d/dx(sin(x)) = cos(x)
69 - Added example/sf/erfc_check (thanks to Keith Lofstrom)
71 Script which tests the erfc() special function against computing
72 the integral definition with gsl_integration_qagiu()
74 - Added example/vector/speed
76 This shows a considerable performance boost using Math::GSL::Vectors
77 instead of List::Util when searching for the min and max elements of
78 large sets of random numbers.
80 - Fixed return signature of gsl_deriv_* functions to return a flat list
81 - Fixed some failing tests relating to -Duselongdouble (Sisyphus)
82 - Fix location of shared objects (Sisyphus)
83 - Added raw() method to RNG objects
85 =head1 v0.12 - September 14 2008
88 - Minimum Perl version changed to 5.8.0
89 - Make platform check compile time constants for performance
90 aka The Wilhelm Speedup (thanks to Eric Wilhelm <scratchcomputing@gmail.com>)
92 - Numerical derivatives fully implemented
93 - Integration subsystem, gsl_integrate_qags() and gsl_integrate_qagi(), etc..
94 - QNG : Non-adaptive Gaussian (uses fixed number of sample points in interval)
95 - QAG(S) : Adaptive Gaussian (Singluar) (slices interval up based on properties of the function)
96 - QAGI : Adaptive Gaussian with infinite integration range
97 - other are supported but not tested
99 - Initial Multiroots tests
100 - More nan/inf fixes on MSWin32 from <sisyphus@cpan.org>
101 - Stripping of binaries on Windows, which significantly reduces size
102 from <sisyphus@cpan.org>
103 - Full support and tests for all functions in the Sort subsystem
104 - Added 'examples/benchmark/sort' to show performance of gsl_sort()
105 - Added 'examples/clicker/chart' to show graphing of functions
106 - Added 'examples/gsl_repl' which is a rapid protyping tool/interactive interpreter
107 - Compile support for GSL's as old as 1.8 (test suite still needs to be properly guarded)
111 - Continued porting to MSWin32, fixing many NaN and Inf handling issues
115 - Large documentation improvements
116 - MSWin32 support thanks to testing and feedback from <sisyphus@cpan.org>
120 - Initial CPAN release
124 - Started change to Test::Class
128 - Added swig interface files and swig-ified build script
129 - initial tests for special function library gsl_sf <--> Math::GSL::Sf
130 - Proof Of Concept: makegsl and testgsl
