Digital Library of Periodicals of National Academy of Sciences of Ukraine| Zusammenfassung: | A new efficient technique for evaluation of complex error function of the real argument on the base of the Euler-Maclaurin formula and a non-singular formula for the principal value of the Cauchy integral is given. . It is demonstrated that for the real values of argument, which are most “expensive” in the computational time, the new algorithm is almost two times faster than algorithm 680 with the same accuracy. The code was successfully implemented to ray tracing code that is used for application for investigation of ICR plasma heating in JET-type tokamaks. |
