an unbiased error variable ε ∼ **N ( 0 ,** 1 2 ) {\textstyle \varepsilon \sim {\mathcal Φ 8}(0,\,{\frac Φ 7 Φ 6})} , erf(x) describes the probability of the error Also has erfi for calculating i erf ( i x ) {\displaystyle i\operatorname {erf} (ix)} Maple: Maple implements both erf and erfc for real and complex arguments. Generalized error functions[edit] Graph of generalised error functions En(x): grey curve: E1(x) = (1−e−x)/ π {\displaystyle \scriptstyle {\sqrt {\pi }}} red curve: E2(x) = erf(x) green curve: E3(x) blue curve: E4(x) Positive integer values of Im(f) are shown with thick blue lines.

Applications[edit] When the results of a series of measurements are described by a normal distribution with standard deviation σ {\displaystyle \textstyle \sigma } and expected value 0, then erf ( a Comp. 23 (107): 631–637. Matlab provides both erf and erfc for real arguments, also via W.
