| [h4 Boost-1.45.0] |
| |
| * Added warnings about potential ambiguity with std random library in distribution and function names. |
| * Added inverse gamma distribution and inverse chi_square and scaled inverse chi_square. |
| * Editorial revision of documentation, and added FAQ. |
| |
| [h4 Boost-1.44.0] |
| |
| * Fixed incorrect range and support for Rayleigh distribution. |
| * Fixed numerical error in the quantile of the Student's T distribution: the function was |
| returning garbage values for non-integer degrees of freedom between 2 and 3. |
| |
| [h4 Boost-1.41.0] |
| |
| * Significantly improved performance for the incomplete gamma function and its inverse. |
| |
| [h4 Boost-1.40.0] |
| |
| * Added support for MPFR as a bignum type. |
| * Added some full specializations of the policy classes to reduce compile times. |
| * Added logistic and hypergeometric distributions, from Gautam Sewani's Google Summer of Code project. |
| * Added Laplace distribution submitted by Thijs van den Berg. |
| * Updated performance test code to include new distributions, and improved the performance of the non-central distributions. |
| * Added SSE2 optimised __lanczos code, from Gautam Sewani's Google Summer of Code project. |
| * Fixed bug in cyl_bessel_i that used an incorrect approximation for [nu] = 0.5, also effects the non-central |
| Chi Square Distribution when [nu] = 3, see bug report [@https://svn.boost.org/trac/boost/ticket/2877 #2877]. |
| * Fixed minor bugs [@https://svn.boost.org/trac/boost/ticket/2873 #2873]. |
| |
| [h4 Boost-1.38.0] |
| |
| * Added Johan R'''å'''de's optimised floating point classification routines. |
| * Fixed code so that it compiles in GCC's -pedantic mode (bug report |
| [@https://svn.boost.org/trac/boost/ticket/1451 #1451]). |
| |
| [h4 Boost-1.37.0] |
| |
| * Improved accuracy and testing of the inverse hypergeometric functions. |
| |
| [h4 Boost-1.36.0] |
| |
| * Added Noncentral Chi Squared Distribution. |
| * Added Noncentral Beta Distribution. |
| * Added Noncentral F Distribution. |
| * Added Noncentral T Distribution. |
| * Added Exponential Integral Functions. |
| * Added Zeta Function. |
| * Added Rounding and Truncation functions. |
| * Added Compile time powers of runtime bases. |
| * Added SSE2 optimizations for Lanczos evaluation. |
| |
| [h4 Boost-1.35.0: Post Review First Official Release] |
| |
| * Added Policy based framework that allows fine grained control |
| over function behaviour. |
| * [*Breaking change:] Changed default behaviour for domain, pole and overflow errors |
| to throw an exception (based on review feedback), this |
| behaviour can be customised using __Policy's. |
| * [*Breaking change:] Changed exception thrown when an internal evaluation error |
| occurs to boost::math::evaluation_error. |
| * [*Breaking change:] Changed discrete quantiles to return an integer result: |
| this is anything up to 20 times faster than finding the true root, this |
| behaviour can be customised using __Policy's. |
| * Polynomial/rational function evaluation is now customisable and hopefully |
| faster than before. |
| * Added performance test program. |
| |
| [h4 Milestone 4: Second Review Candidate (1st March 2007)] |
| |
| * Moved Xiaogang Zhang's Bessel Functions code into the library, |
| and brought them into line with the rest of the code. |
| * Added C# "Distribution Explorer" demo application. |
| |
| [h4 Milestone 3: First Review Candidate (31st Dec 2006)] |
| |
| * Implemented the main probability distribution and density functions. |
| * Implemented digamma. |
| * Added more factorial functions. |
| * Implemented the Hermite, Legendre and Laguerre polynomials plus the |
| spherical harmonic functions from TR1. |
| * Moved Xiaogang Zhang's elliptic integral code into the library, |
| and brought them into line with the rest of the code. |
| * Moved Hubert Holin's existing Boost.Math special functions |
| into this library and brought them into line with the rest of the code. |
| |
| [h4 Milestone 2: Released September 10th 2006] |
| |
| * Implement preview release of the statistical distributions. |
| * Added statistical distributions tutorial. |
| * Implemented root finding algorithms. |
| * Implemented the inverses of the incomplete gamma and beta functions. |
| * Rewrite erf/erfc as rational approximations (valid to 128-bit precision). |
| * Integrated the statistical results generated from |
| the test data with Boost.Test: uses a database of expected |
| results, indexed by test, floating point type, platform, and compiler. |
| * Improved lgamma near 1 and 2 (rational approximations). |
| * Improved erf/erfc inverses (rational approximations). |
| * Implemented Rational function generation (the Remez method). |
| |
| [h4 Milestone 1: Released March 31st 2006] |
| |
| * Implement gamma/beta/erf functions along with their incomplete counterparts. |
| * Generate high quality test data, against which future improvements can be judged. |
| * Provide tools for the evaluation of infinite series, continued fractions, and |
| rational functions. |
| * Provide tools for testing against tabulated test data, and collecting statistics |
| on error rates. |
| * Provide sufficient docs for people to be able to find their way around the library. |
