Interpolation has wide application in signal processing, numerical integration, Computer Aided Geometric Design (CAGD), engineering technology and electrochemistry. Block based bivariate Newton-like blending rational interpolation can also be calculated based on information matrix algorithm in addition to block divided differences. The paper studied interpolation theorem, dual interpolation of ...

Numerical operations on and among rational matrices are traditionally handled by direct manipulation with their scalar entries. A new numerically attractive alternative is proposed here that is based on rational matrix interpolation. The procedure begins with evaluation of rational matrices in several complex points. Then all the required operations are performed consecutively on constant matri...

We address the problem of data independent robust array interpolation over large angular sectors. Previous interpolation methods apply the root-MUSIC principle to interpolation data of a predefined virtual ULA manifold. These methods either suffer from severely biased direction-ofarrival estimates due to interpolation errors or rely on data dependent interpolation matrix design. In this paper a...
