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