is the double factorial: the product of all odd numbers up to (2n–1). If you want to compute the inverse error function for a complex number, use sym to convert that number to a symbolic object, and then call erfinv for that symbolic object.If Home/ Special Function/ Error function Inverse error function Calculator Calculates the inverse error function erf -1(y) and inverse complementary error function erfc -1(y).

These generalised functions can equivalently be expressed for x>0 using the Gamma function and incomplete Gamma function: E n ( x ) = 1 π Γ ( n ) ( Γ Online Integral Calculator» Solve integrals with Wolfram|Alpha. Perl: erf (for real arguments, using Cody's algorithm[20]) is implemented in the Perl module Math::SpecFun Python: Included since version 2.7 as math.erf() and math.erfc() for real arguments. For real values x, the toolbox applies these simplification rules:erfinv(erf(x)) = erfinv(1 - erfc(x)) = erfcinv(1 - erf(x)) = erfcinv(erfc(x)) = xerfinv(-erf(x)) = erfinv(erfc(x) - 1) = erfcinv(1 + erf(x)) =
