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