# 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)
1. Compute the scaled complementary error function of a number:

julia> erfcx(0.5)
1.2074502803173123

This example calculates the erfcx value for the number 0.5.

2. 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).
