摘要
用复分析和矩阵方程理论给出C auchy矩阵求逆公式的一种新证明.作为应用,研究与H erm ite-C auchy矩阵相关的N evan linna-P ick插值问题,给出该插值问题全部解的简洁表示.
The inversion formula of a Cauehy matrix is proved in a different way from the adjoint matrix approach, which is by means of Complex Analysis and matrix equation theory. As an application, the solutions for tackling a certain type of the Nevanlinna- Pick （NP） interpolation problems involving Hermite Cauchy matrices are expressed briefly as well.
