The error function is related to the cumulative distribution Φ {\displaystyle \Phi } , the integral of the standard normal distribution, by[2] Φ ( x ) = 1 2 + 1 The defining integral cannot be evaluated in closed form in terms of elementary functions, but by expanding the integrand e−z2 into its Maclaurin series and integrating term by term, one obtains Show that the numbers follow the form of the Gaussian distribution using a histogram plot.rng('default') x = -1 + 2*rand(1,10000); y = sqrt(2)*erfinv(x); h = histogram(y); Input Argumentscollapse allx -- Inputreal Inverse Complementary Error Function For complex, the Faddeeva package provides a C++ complex implementation.

The integrand ƒ=exp(−z2) and ƒ=erf(z) are shown in the complex z-plane in figures 2 and 3. Inverse Error Function Excel Go: Provides math.Erf() and math.Erfc() for float64 arguments. All generalised error functions for n>0 look similar on the positive x side of the graph. see it here Wolfram Knowledgebase Curated computable knowledge powering Wolfram|Alpha.
