Complex Error Function
 

Hi, friends:

I got a question on trying to solve unsteady diffusion problem using Green's function method, where I found that the Green's function in my case involves complex error function,

such as: erf(a+b i),

do you know how complex error function can be calculated?

thanks,

Wen

A complex error function is simply an incomplete gamma function. See the mathematica website:

I think they should be easy to calculate by recurrence relations, but I have never done this before.
