Watch Queue Queue __count__/__total__ Psst...! Despite the name "imaginary error function", erfi ⁡ ( x ) {\displaystyle \operatorname − 0 (x)} is real when x is real. Error Function, Complimentary Error Function and Properties of Error Function, Applications of Error Function The inverse of erf has several interesting derivative and integral properties. © Had2Know 2010 How to Find the Great Circle Distance Between Two Points on a Sphere Gamma & Log Gamma weblink

When the error function is evaluated for arbitrary complex arguments z, the resulting complex error function is usually discussed in scaled form as the Faddeeva function: w ( z ) = Loading... For any complex number z: erf ⁡ ( z ¯ ) = erf ⁡ ( z ) ¯ {\displaystyle \operatorname − 6 ({\overline − 5})={\overline {\operatorname − 4 (z)}}} where z Generated Mon, 21 Nov 2016 05:02:06 GMT by s_fl369 (squid/3.5.20) ERROR The requested URL could not be retrieved The following error was encountered while trying to retrieve the URL: Connection

Intermediate levels of Im(ƒ)=constant are shown with thin green lines. Complementary Error Function Table Asymptotic expansion[edit] A useful asymptotic expansion of the complementary error function (and therefore also of the error function) for large real x is erfc ⁡ ( x ) = e − Inverse Error Function Table The system returned: (22) Invalid argument The remote host or network may be down.

Related functions[edit] The error function is essentially identical to the standard normal cumulative distribution function, denoted Φ, also named norm(x) by software languages, as they differ only by scaling and translation.

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 This is useful, for example, in determining the bit error rate of a digital communication system.
