Transformations If the arguments of the probability integrals , , and contain square roots, the arguments can sometimes be simplified: Representations of derivatives The derivative of the probability integrals , , We obtain a very good approximation of $\operatorname{inverf}(x)$ through a high-order Taylor expansion around $x=0$. The error function at +∞ is exactly 1 (see Gaussian integral). All generalised error functions for n>0 look similar on the positive x side of the graph.

In rare instances, a publisher has elected to have a "zero" moving wall, so their current issues are available in JSTOR shortly after publication. Error Function Matlab 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 ) =

For |z| < 1, we have erf ( erf − 1 ( z ) ) = z {\displaystyle \operatorname ζ 2 \left(\operatorname ζ 1 ^{-1}(z)\right)=z} . Complementary Error Function Table I also found out that is it okay to put z -> iz in the series above (2) and it fits with result obtained from Maple. –George Nov 7 '14 at Read as much as you want on JSTOR and download up to 120 PDFs a year.

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 − At the real axis, erf(z) approaches unity at z→+∞ and −1 at z→−∞.
