摘要: In this work we show a rational approximation of the Dawsons integral that can be implemented for high accuracy computation complex error function in rapid algorithm. Specifically, approach provides exceeding 1014 domain practical importance 0y<0.1|x+iy|8. A Matlab code with entire coverage plane is presented.
