The
table and diagram below show the form of the Gaussian error function. For
diffusion processes, the argument of the function, z
= x / 2(Dt)0.5,
is dimensionless, and the error function is defined as:
The complementry error function, efrc, is (1 - erf(z)). For z = 2, erf (z) -> 1 and efrc -> 0. |
