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