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