Your cache administrator is webmaster. Mathematica: erf is implemented as Erf and Erfc in Mathematica for real and complex arguments, which are also available in Wolfram Alpha. This is useful, for example, in determining the bit error rate of a digital communication system. http://blogeurope.net/error-function/gauss-error-function-python.php The error function is related to the cumulative distribution Φ {\displaystyle \Phi } , the integral of the standard normal distribution, by[2] Φ ( x ) = 1 2 + 1

Matlab provides both erf and erfc for real arguments, also via W. How To Calculate Error Function In Casio Calculator Continued fraction expansion[edit] A continued fraction expansion of the complementary error function is:[11] erfc ⁡ ( z ) = z π e − z 2 1 z 2 + a 1 Intermediate levels of Re(ƒ)=constant are shown with thin red lines for negative values and with thin blue lines for positive values.

For previous versions or for complex arguments, SciPy includes implementations of erf, erfc, erfi, and related functions for complex arguments in scipy.special.[21] A complex-argument erf is also in the arbitrary-precision arithmetic

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 Both functions are overloaded to accept arguments of type float, double, and long double.

For complex double arguments, the function names cerf and cerfc are "reserved for future use"; the missing implementation is provided by the open-source project libcerf, which is based on the Faddeeva Cody's rational Chebyshev approximation algorithm.[20] Ruby: Provides Math.erf() and Math.erfc() for real arguments.

After division by n!, all the En for odd n look similar (but not identical) to each other. This allows one to choose the fastest approximation suitable for a given application.
