Description
The function cdawson 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).
For function dawson takes a real argument x, and returns the real result D(x).
Name

See Also
The computation of D(z) is based on Faddeeva's function w_of_z(3); to compute D(x), the imaginary part
im_w_of_x(3) is used.
Other complex error functions: w_of_z(3), voigt(3), cerf(3), erfcx(3), erfi(3).
