New approach for 2-D spectrum estimation——parameter weight method

open access: yesTongxin xuebao, 2006
A new approach of 2-D MUSIC algorithm was proposed.Using the eigenvector and the eigenvalue of the co-variance matrix simultaneously,the method was composed of two one-dimension searching and avoided the costly 2-D searching.The pairings of the estimated

Eigenvectors of certain matrices

open access: yesLinear Algebra and its Applications, 1973
AbstractAn algorithm is given for calculation of eigenvalues and eigenvectors of centrosymmetric and some related matrices, and some desirable properties of the algorithm are proved. Centrosymmetric matrices are characterized by a symmetry property of their eigenvectors and this result is used to establish a property of certain methods for the ...

Graph partitioning by Eigenvectors

open access: yesLinear Algebra and its Applications, 1988
Given a graph G on n vertices and \(z\in R^ n\), we say that a vertex of G is positive, nonnegative, null, etc. if the corresponding entry of z has that property. For z such that Az\(\geq \alpha z\) (A is the adjacency matrix of G) the number of components of the subgraph induced by positive vertices is bounded.

Proposing a method to achieve the weights in Fuzzy-MCDM problems: a case study due to select a type of tickicide [PDF]

open access: yesMuṭāli̒āt-i Mudīriyyat-i Ṣan̒atī, 2006
This paper extends a kind of evaluation process based on fuzzy TOPS IS approach. By focusing on determining the importance and weights of criteria which are effective on decision making , then selecting by lean on Anthropy and eigenvector methods in ...

Asymptotic Inference for Eigenvectors

open access: yesThe Annals of Statistics, 1981
Abstract : Asymptotic procedures are given for testing certain hypotheses concerning eigenvectors and for constructing confidence regions for eigenvectors. These asymptotic procedures are derived under fairly general conditions on the estimates of the matrix whose eigenvectors are of interest. Applications of the general results to principal components
