erf

erf(x)

Compute the error function of x, defined by $\frac{2}{\sqrt{\pi}} \int_0^x e^{-t^2} dt$ for arbitrary complex x.

Examples

julia> A = rand(10,5)
       b = rand(10)
       x = A \ b
       B = A' * A
       erf(eigvals(B)) - 2x.^2 + 4x - 6

5-element Array{Float64,1}:
 -6.29936
 -3.67082
 -8.87201
 -3.20876
 -4.82683
