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