Apr 30, 2025 · 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.

The error function and the complementary error function are important special functions which appear in the solutions of di usion problems in heat, mass and momentum transfer, probability …

The complementary error function represents the area under the two tails of a zero-mean Gaussian probability density function with variance 2 = 1=2, as illustrated in Fig. 1.

For large values of x (>3), the complementary error function can be approximated by: The error in the approximation is about -2% for x=3, and -1% for x=4, and gets progressively better with …

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.
