<h1><a name="description">DESCRIPTION</a></h1>
<p>The function <strong>cdawson</strong> returns Dawson's integral D(z) = exp(-z^2) integral from 0 to z exp(t^2) dt = sqrt(pi)/2 * exp(-z^2) * erfi(z).</p>
<p>For function <strong>dawson</strong> takes a real argument x, and returns the real result D(x).</p>

<h1><a name="references">REFERENCES</a></h1>
<p>The computation of D(z) is based on Faddeeva's function <strong>w_of_z</strong>; to compute D(x), the imaginary part <strong>im_w_of_x</strong> is used.</p>
