3 Plasma dispersion function Z(x) Plasma dispersion function Z(x) (Fried and Conte, 1961) is also called Fried-Conte function (Baumjohann and Treumann, 1997, p. 268). In the book by Mikhailovskiy (1975), notation is ZMikh(x) ≡ xZ(x), which may be a source of confusion. Plasma dispersion function is defined as: Z(x) = 1 √ π Z+∞ −∞ e ...

integrands considered in this book are analytic functions, the results of integration do not depend on the integration contours; it is only important how these trajectories approach infinity.

27.11.2019 · The error function (erf) is a special function which gets its name for its importance in the study of errors. It is sometimes called the Gauss Function.

The error function is also closely related to the Gaussian probability functions: 6. erf (x)=2P(xV2)-1=A(xY2). 3.2. Integral Representations. 2az II.

• Abramowitz and Stegungive several approximations of varying accuracy (equations 7.1.25–28). This allows one to choose the fastest approximation suitable for a given application. In order of increasing accuracy, they are: (maximum error: 5×10 ) where a1 = 0.278393, a2 = 0.230389, a3 = 0.000972, a4 = 0.078108 (maximum error: 2.5×10 ) where p = 0.47047, a1 = 0.3480242, a2 = −0.0958798, a3 = 0.7478556 erf ⁡ x ≈ 1 − 1 ( 1 + a 1 x + a 2 x 2 + ⋯ + a 6 x 6 ) 16 , x ≥ 0 {\displayst…
