摘要: 给出了一种计算两个特殊行列式的算法.这两个行列式是构造第二类Fredholm积分方程解的函数值Padé 型逼近的行列式公式,一般计算行列式的算法对于这两个行列式的计算较难实现,该文主要利用著名的Schur补定理解决了这一问题.

Abstract: In this paper, computation of two special determinants that appear in the constr uction of a function valued Padé type approximation for computing the second kind Fredholm integral equation is investigated. Since the common computational approach of determinant cannot be used in this case, the well known Schur complement theorem is used in this paper.
