ERF function
ERF(x) returns the error function integrated between zero and x. The result is in the range (−1, 1); it approaches 1 as x → +∞ and −1 as x → −∞.
$$\operatorname{erf}(x) = \frac{2}{\sqrt{\pi}}\int_{0}^x e^{-t^2}\,\mathrm dt$$
$$\operatorname{erf}(x) = \frac{2}{\sqrt{\pi}}\int_{0}^x e^{-t^2}\,\mathrm dt$$
The argument x can be a real number or a matrix. When it is a matrix, the function returns a matrix with the same dimensions and with the ERF function applied to all elements.
Examples
ERF(0) equals 0
ERF(1) equals 0.8427008
