| Hubert Holin started the Boost.Math library. The inverse hyperbolic functions, |
| and the sinus cardinal functions are his. |
| </p> |
| <p> |
| John Maddock started this library, the beta, gamma, erf, polynomial, and |
| factorial functions are his, as is the "Toolkit" section, and many |
| of the statistical distributions. |
| </p> |
| <p> |
| Paul A. Bristow threw down the challenge in <a href="http://www2.open-std.org/JTC1/SC22/WG21/docs/papers/2004/n1668.pdf" target="_top">A |
| Proposal to add Mathematical Functions for Statistics to the C++ Standard |
| Library</a> to add the key math functions, especially those essential |
| for statistics. After JM accepted and solved the difficult problems, not |
| only numerically, but in full C++ template style, PAB implemented a few of |
| the statistical distributions. PAB also tirelessly proof-read everything |
| that JM threw at him (so that all remaining editorial mistakes are his fault). |
| </p> |
| <p> |
| Xiaogang Zhang worked on the Bessel functions and elliptic integrals for |
| his Google Summer of Code project 2006. |
| </p> |
| <p> |
| Bruno Lalande submitted the "compile time power of a runtime base" |
| code. |
| </p> |
| <p> |
| Johan Råde wrote the optimised floating-point classification and manipulation |
| code, and nonfinite facets to permit C99 output of infinities and NaNs. (nonfinite |
| facets were not added until Boost 1.47 but had been in use with Boost.Spirit). |
| This library was based on a suggestion from Robert Ramey, author of Boost.Serialization. |
| Paul A. Bristow expressed the need for better handling of <a href="http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2006/n2022.pdf" target="_top">Input |
| & Output of NaN and infinity for the C++ Standard Library</a> and |
| suggested following the C99 format. |
| </p> |
| <p> |
| Håkan Ardö, Boris Gubenko, John Maddock, Markus Schöpflin and Olivier Verdier |
| tested the floating-point library and Martin Bonner, Peter Dimov and John |
| Maddock provided valuable advice. |
| </p> |
| <p> |
| Gautam Sewani coded the logistic distribution as part of a Google Summer |
| of Code project 2008. |
| </p> |
| <p> |
| M. A. (Thijs) van den Berg coded the Laplace distribution. (Thijs has also |
| threatened to implement some multivariate distributions). |
| </p> |
| <p> |
| Thomas Mang requested the inverse gamma in chi squared distributions for |
| Bayesian applications and helped in their implementation. |
| </p> |
| <p> |
| Professor Nico Temme for advice on the inverse incomplete beta function. |
| </p> |
| <p> |
| <a href="http://www.shoup.net" target="_top">Victor Shoup for NTL</a>, without which |
| it would have much more difficult to produce high accuracy constants, and |
| especially the tables of accurate values for testing. |
| </p> |
| <p> |
| We are grateful to Joel Guzman for helping us stress-test his <a href="http://www.boost.org/tools/quickbook/index.htm" target="_top">Boost.Quickbook</a> |
| program used to generate the html and pdf versions of this document, adding |
| several new features en route. |
| </p> |
| <p> |
| Thanks to Mark Coleman and Georgi Boshnakov for spot test values from <a href="http://www.wolfram.com/products/mathematica/index.html" target="_top">Wolfram Mathematica</a>, |
| and of course, to Eric Weissten for nurturing <a href="http://mathworld.wolfram.com" target="_top">Wolfram |
| MathWorld</a>, an invaluable resource. |
| </p> |
| <p> |
| Plots of the functions and distributions were prepared in <a href="http://www.w3.org/" target="_top">W3C</a> |
| standard <a href="http://www.svg.org/" target="_top">Scalable Vector Graphic (SVG)</a> |
| format using a program created by Jacob Voytko during a <a href="http://code.google.com/soc/2007/" target="_top">Google |
| Summer of Code (2007)</a>. Since browser support for rendering SVG is |
| still not universal (Microsoft Internet Explorer, even IE 8 beta, still lacks |
| native SVG support but can be made to work with <a href="http://www.adobe.com/svg/viewer/install/" target="_top">Adobe's |
| free SVG viewer</a> plugin), so the SVG files were batch converted to |
| JPEG using <a href="http://www.inkscape.org/" target="_top">Inkscape</a>. |
| </p> |
| <p> |
| We are also indebted to Matthias Schabel for managing the formal Boost-review |
| of this library, and to all the reviewers - including Guillaume Melquiond, |
| Arnaldur Gylfason, John Phillips, Stephan Tolksdorf and Jeff Garland - for |
| their many helpful comments. |
