Math. Formula or Function? The error and complementary error functions occur, for example, in solutions of the heat equation when boundary conditions are given by the Heaviside step function. Taylor series[edit] The error function is an entire function; it has no singularities (except that at infinity) and its Taylor expansion always converges. http://www.office-forums.com/threads/the-inverse-error-function-erfinv.862363/

Cody's algorithm.[20] Maxima provides both erf and erfc for real and complex arguments. Inverse Error Function Python Cody's rational Chebyshev approximation algorithm.[20] Ruby: Provides Math.erf() and Math.erfc() for real arguments. The defining integral cannot be evaluated in closed form in terms of elementary functions, but by expanding the integrand e−z2 into its Maclaurin series and integrating term by term, one obtains It is related to inverse erf by (2) It has the special values (3) (4) (5) It has the derivative (6) and its indefinite integral is (7) (which follows from the
