论文摘要
在这项工作中,我们开发了一种新算法,用于有效地计算VOIGT/复杂误差函数。特别是,在这种方法中,我们提出了一个两域方案,其中插值网格点的数量取决于输入参数$ y $。我们执行的错误分析表明,MATLAB实现符合涉及Hitran分子光谱数据库的辐射转移应用的要求。运行时测试表明,此MATLAB实现提供了快速计算,尤其是在参数$ x $的较小范围内。
In this work we develop a new algorithm for the efficient computation of the Voigt/complex error function. In particular, in this approach we propose a two-domain scheme where the number of the interpolation grid-points is dependent on the input parameter $y$. The error analysis we performed shows that the MATLAB implementation meets the requirements for radiative transfer applications involving the HITRAN molecular spectroscopic database. The run-time test shows that this MATLAB implementation provides rapid computation, especially at smaller ranges of the parameter $x$.
