The system returned: (22) Invalid argument The remote host or network may be down. 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 − http://mathworld.wolfram.com/InverseErfc.html

After division by n!, all the En for odd n look similar (but not identical) to each other. 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 Level of Im(ƒ)=0 is shown with a thick green line.

Some authors discuss the more general functions:[citation needed] E n ( x ) = n ! π ∫ 0 x e − t n d t = n ! π ∑ 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

- The relationship between the inverse complementary error function erfcinv and norminv isnorminv(p)=(−2)×erfcinv(2p).For expressions of the form erfcinv(1-x), use the inverse error function erfinv instead.
- However, it can be extended to the disk |z| < 1 of the complex plane, using the Maclaurin series erf − 1 ( z ) = ∑ k = 0
- 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
