本文介绍了一种快速、稳健的频域响应有理拟合方法，适用于标量传递函数和矢量传递函数。新方法的应用提高了采用频率相关变换矩阵进行模式分解的传输线模型的计算效率。这是因为该方法允许每个特征向量的拟合元素共享相同的极点集，并且可以用相对较少的极点数来实现准确的拟合。
This paper introduces a fast and robust method for rational fitting of frequency domain responses, well suited for both scalar and vector transfer functions. Application of the new method results in increased computational efficiency for transmission line models using modal decomposition with frequency dependent transformation matrices. This is due to the fact that the method allows the fitted elements of each eigenvector to share the same set of poles, and that accurate fitting can be achieved with a relatively low number of poles.
