Computing of Voigt/complex error function with small y

This program file is presented for highly accurate approximation of the Voigt/complex error function with small imaginary argument y ≤ 0.1.

[Kxy,Lxy]=cedawSeu(x,y).

This program file computes the complex error function with small imaginary argument 0≤y≤ 0.1.

In the real and imaginary parts this program provides average accuracy exceeding 1e-15 and 1e-16, respectively.
