Erfc -- from Wolfram MathWorld
5 天之前 · Erfc is the complementary error function, commonly denoted erfc(z), is an entire function defined by erfc(z) = 1-erf(z) (1) = 2/(sqrt(pi))int_z^inftye^(-t^2)dt. (2) It is implemented …

Erfc—Wolfram Language Documentation
Mathematical function, suitable for both symbolic and numerical manipulation. Erfc [ z ] is given by . For certain special arguments, Erfc automatically evaluates to exact values.
erfc - MathWorks
erfc(x) returns the Complementary Error Function evaluated for each element of x. Use the erfc function to replace 1 - erf(x) for greater accuracy when erf(x) is close to 1.
The complementary error function erfc(x) is plotted in Fig. 2, along with an upper and a lower bound (established in Appendix A). The bounds are asymptotically tight, i.e., the di erence …
Function (noted erfc) is defined by the following second order differential equation 2x ∂y(x) ∂x + ∂2y(x) ∂x2 (ERFC.1.1) = 0. The initial conditions of ERFC.1.1 are given at 0 by erfc(0) = 1, …
