Intermediate levels **of Im(ƒ)=constant** are shown with thin green lines. For any complex number z: erf ( z ¯ ) = erf ( z ) ¯ {\displaystyle \operatorname − 0 ({\overline 9})={\overline {\operatorname 8 (z)}}} where z Using the alternate value a≈0.147 reduces the maximum error to about 0.00012.[12] This approximation can also be inverted to calculate the inverse error function: erf − 1 ( x ) Please join our friendly community by clicking the button below - it only takes a few seconds and is totally free.

Perl: erf (for real arguments, using Cody's algorithm[20]) is implemented in the Perl module Math::SpecFun Python: Included since version 2.7 as math.erf() and math.erfc() for real arguments. Ch.5 in Combinatorial Species and Tree-Like Structures.

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 Matlab provides both erf and erfc for real arguments, also via W.
