Error function Plot of the error function From Wikipedia, the free encyclopedia In mathematics, the error function (also called the Gauss error function ) is a special function (non-elementary) which occurs in probability, statistics, materials science, and partial differential equations. It is defined as: The complementary error function , denoted erfc , is defined in terms of the error function: The complex error function , denoted w ( x ), (also known as the Faddeeva function) is also defined in terms of the error function: Contents 1 Properties 1.1 Taylor series 1.2 Inverse function 2 Applications 2.1 Asymptotic expansion 2.2 Approximation with elementary functions 3 Related functions 3.1 Generalised error functions 3.2 Iterated integrals of the complementary error function 4 Implementation 5 Table of values 6 See also 7 References 8 External links Properties Error function - Wikipedia, the free encyclopedia http://en.wikipedia.org/wiki/Error_function 1 of 8 2/2/2009 11:08 PM
