Math Reference Sites
 Digital Library of Mathematical Functions: A special function reference site that aims to be the nextgeneration Abromowitz & Stegun.
 Mathworld: Eric Weisstein's encylopedia of math topics. Not as wellmaintained as it once was, but still a useful compliment to Wikipedia.
 Wolfram Functions: A compendium of properties of special functions.
Other .NET Numerical Libraries
 Math.NET: Another free .NET library, probably our closest competitor. Offers some interpolation and matrix functionality that we lack, lacks
some data wrangling, statistics, fitting, special function, and solver functionality that we offer.
 Extreme Optimization: A commercial library with a wellorganized API and a lot of functionality. Retails for about $1000/developer.
 NMath: A commercial library with a lot of functionality and a notsoorganized API structure. Retails for about $1300/developer.
 IMSL C#: A commercial library with a pedigree stretching back to the 1970s which has now been
ported to .NET.
Notable Numerical Libraries On Other Platforms
 GNU Scientific Library: A C library maintained since the 1990s.
 MPMath: A python library for computing special functions to arbitrary precision.
 LAPACK: The standard linear algebra library, in FORTRAN.

Papers
 Goldberg, David, What Every Computer Scientist Should Know About FloatingPoint Arithmetic, 1991:
A very indepth guide to floatingpoint, very useful but actually far more than any typical programmer would be expected to know about floatingpoint.
 Kahan, Branch Cuts for Complex Elementary Functions, or Much Ado About Nothing's Sign Bit:
Algorithms for basic complex functions.
 Bailey, Borwein, and Crandall, Advanced in the Theory of Box Integrals, 2009:
Analytic solutions (found by experiment) to difficult multidimensional integrals. We use these as testcases of our multidimensional integration logic.
 Powell, UOBYQA: Unconstrained Optimization by Quadratic Approximation, 2000:
Our derivativefree algorithm for unconstrained local optimization is based on this paper.
