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