Jablonski, A. Improved algorithm for calculating the Chandrasekhar function. (English) Zbl 1306.82002 Comput. Phys. Commun. 184, No. 2, 440-442 (2013). Summary: Theoretical models of electron transport in condensed matter require an effective source of the Chandrasekhar \(H(x,omega)\) function. A code providing the \(H(x,omega)\) function has to be both accurate and very fast. The current revision of the code published earlier [A. Jablonski, Comput. Phys. Commun. 183, No. 8, 1773–1782 (2012; Zbl 1305.82007)] decreased the running time, averaged over different pairs of arguments \(x\) and \(omega\), by a factor of more than 20. The decrease of the running time in the range of small values of the argument \(x\), less than \(0.05\), is even more pronounced, reaching a factor of 30. The accuracy of the current code is not affected, and is typically better than 12 decimal places.
