erfcx

Arguments

x

vector or matrix

y

vector or matrix (of same size than x)

Description

Compute the scaled complementary error function of x, defined by exp(x2).erfc(x). Note also that erfcx(-ix) computes the Faddeeva function w(x).

Examples

x = [1+2*%i,-1+2*%i,1e-6+2e-6*%i,0+2*%i];
erfcx(x)
// Equivalent to
exp (x.^2) .* erfc(x)

Algorithms

This function is based on the Faddeeva package library.
