摘要
一个基本的“Loewner矩阵-Hahael向量”关系被用以推导广义Loewner矩阵（不必为方阵，但对应于同一有理插值问题）的核结构定理与它的因子分解，此分解涉及到广义Cauchy－Vandermonde矩阵．
A foundational 'Loewner matrix- Hankel vector' connection is used to derive a kernel structure theorem for the generalized Loewner matrixs (not necesarily square) associated with a rational interpolation problem and a factorization for such matrices by means of generalized Cauchy- Vandermonde matrices.
