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
16 =head1 v0.14 - October 21 2008
17 - Chebyshev Series Approximation, with tests and docs
18 - Examples and new documentation in Statistics, as well as tests (Thierry)
19 - Bugfixes relating to compiling on 64bit Red Hat Linux, reported by Michael Roberge
20 - Improved FFT, Deriv, Integration, Chebyshev, Combination and Roots docs
21 - Documentation for Math::GSL::Test
22 - Improved introduction examples in Math::GSL
23 - Improved Minimization subsystem tests, but it is not functional
24 - Added examples/fft/forward_real
25 - Added example/deriv/basic
27 This shows the simple fact that d/dx(sin(x)) = cos(x)
29 - Added example/sf/erfc_check (thanks to Keith Lofstrom)
31 Script which tests the erfc() special function against computing
32 the integral definition with gsl_integration_qagiu()
34 - Added example/vector/speed
36 This shows a considerable performance boost using Math::GSL::Vectors
37 instead of List::Util when searching for the min and max elements of
38 large sets of random numbers.
40 - Fixed return signature of gsl_deriv_* functions to return a flat list
41 - Fixed some failing tests relating to -Duselongdouble (Sisyphus)
42 - Fix location of shared objects (Sisyphus)
43 - Added raw() method to RNG objects
45 =head1 v0.12 - September 14 2008
48 - Minimum Perl version changed to 5.8.0
49 - Make platform check compile time constants for performance
50 aka The Wilhelm Speedup (thanks to Eric Wilhelm <scratchcomputing@gmail.com>)
52 - Numerical derivatives fully implemented
53 - Integration subsystem, gsl_integrate_qags() and gsl_integrate_qagi(), etc..
54 - QNG : Non-adaptive Gaussian (uses fixed number of sample points in interval)
55 - QAG(S) : Adaptive Gaussian (Singluar) (slices interval up based on properties of the function)
56 - QAGI : Adaptive Gaussian with infinite integration range
57 - other are supported but not tested
59 - Initial Multiroots tests
60 - More nan/inf fixes on MSWin32 from <sisyphus@cpan.org>
61 - Stripping of binaries on Windows, which significantly reduces size
62 from <sisyphus@cpan.org>
63 - Full support and tests for all functions in the Sort subsystem
64 - Added 'examples/benchmark/sort' to show performance of gsl_sort()
65 - Added 'examples/clicker/chart' to show graphing of functions
66 - Added 'examples/gsl_repl' which is a rapid protyping tool/interactive interpreter
67 - Compile support for GSL's as old as 1.8 (test suite still needs to be properly guarded)
71 - Continued porting to MSWin32, fixing many NaN and Inf handling issues
75 - Large documentation improvements
76 - MSWin32 support thanks to testing and feedback from <sisyphus@cpan.org>
80 - Initial CPAN release
84 - Started change to Test::Class
88 - Added swig interface files and swig-ified build script
89 - initial tests for special function library gsl_sf <--> Math::GSL::Sf
90 - Proof Of Concept: makegsl and testgsl
