A Fast Algorithm for Inversion of Confluent Vandermonde-Like Matrices Involving Polynomials that Satisfy a Three-Term Recurrence Relation
Xu Zhong, You Zhaoyong · SIAM Journal on Matrix Analysis and Applications · 1998
The present paper describes a new fast algorithm for inversion of confluent Vandermonde-like matrices. Our algorithm generalizes a scheme presented by Calvetti and Reichel [27] for fast inversion of Vandermonde-like matrices.
