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