erfcx
erfcx(x)
Compute the scaled complementary error function of x,
defined by $e^{x^2} \operatorname{erfc}(x)$. Note
also that $\operatorname{erfcx}(-ix)$ computes the
Faddeeva function $w(x)$.
Examples
julia> erfcx(0.5)
1.2074502803173123
julia> erfcx(-1.0im)
(-1.6506801238857845 - 0.4504470036145381im)-
Compute the scaled complementary error function of a number:
julia> erfcx(0.5) 1.2074502803173123This example calculates the erfcx value for the number 0.5.
- Compute the Faddeeva function using the imaginary number:
julia> erfcx(-1.0im) (-1.6506801238857845 - 0.4504470036145381im)The erfcx function can also be used to compute the Faddeeva function using the imaginary number
-ix.
Please note that the erfcx function computes the scaled complementary error function erfc(x) defined by e^(x^2) * erfc(x). It is worth mentioning that erfcx(-ix) calculates the Faddeeva function w(x).
