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