Compute the Dawson (scaled imaginary error) function.

Syntax

y = dawson(x)

Arguments

x: vector or matrix
y: vector or matrix (of same size than x)

Description

dawson computes scaled imaginary error function function:

$\mathrm{Dawson}(z) = \frac{\sqrt{\pi}}{2} e^{-z^2} \mathrm{erfi}(z)$

Examples

x = [0.1, 1, 1+2*%i,-1+2*%i,1e-4+2e-4*%i,0+2*%i];
dawson(x)
dawson(-x)
