In mathematics, the error function (also called the Gauss error function) is a special function (non-elementary) of sigmoid shape which occurs in probability, statistics and partial differential equations. It is defined as:
The complementary error function, denoted erfc, is defined as
The imaginary error function, denoted erfi, is defined as
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:

Famous quotes containing the words error and/or function:
“Truth on our level is a different thing from truth for the jellyfish, and there must certainly be analogies for truth and error in jellyfish life.”
—T.S. (Thomas Stearns)
“No one, however powerful and successful, can function as an adult if his parents are not satisfied with him.”
