matlab实现Faddeeva函数(基于FFT)

Faddeeva function (FFT based)

W = FADDEEVA(Z) is the Faddeeva function, aka the plasma dispersion function, for each element of Z. The Faddeeva function is defined as:

 

     w(z) = exp(-z^2) erfc(-jz)

 

where erfc(x) is the complex complementary error function.

 

This code is a modified version of the code listed in:
