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