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