A new method for consistency test in fuzzy AHP
收藏 引用
JOURNAL OF INTELLIGENT & FUZZY SYSTEMS 2013年 第2期25卷 457-461页
作者: Mahmoudzadeh, Morteza Bafandeh, Ali R. Islamic Azad Univ East Azarbaijan Sci & Res Branch Dept Management Tabriz Iran Islamic Azad Univ Tabriz Branch Dept Management Tabriz Iran
This paper presents that the consistency test with consideration of a tolerance deviation in fuzzy AHP proposed by L. C. Leung and D. Cao (2000) is not efficient and has some errors, hence a new method of fuzzy consis... 详细信息

FAST COMPUTATION OF THE ZEROS OF A POLYNOMIAL VIA FACTORIZATION OF THE COMPANION MATRIX
收藏 引用
SIAM JOURNAL ON SCIENTIFIC COMPUTING 2013年 第1期35卷 A255-A269页
作者: Aurentz, Jared L. Vandebril, Raf Watkins, David S. Washington State Univ Dept Math Pullman WA 99164 USA Katholieke Univ Leuven Dept Comp Sci B-3001 Heverlee Belgium
A new fast algorithm for computing the zeros of a polynomial in O(n(2)) time using O(n) memory is developed. The eigenvalues of the Frobenius companion matrix are computed by applying a nonunitary analogue of Francis&... 详细信息

A numerical method for computing an SVD-like decomposition
收藏 引用
SIAM JOURNAL ON MATRIX ANALYSIS AND APPLICATIONS 2005年 第4期26卷 1058-1082页
作者: Xu, HG Univ Kansas Dept Math Lawrence KS 66045 USA
We present a numerical method for computing the SVD-like decomposition B = QDS(-1), where Q is orthogonal, S is symplectic, and D is a permuted diagonal matrix. The method can be applied directly to compute the canoni... 详细信息

The BR eigenvalue algorithm
收藏 引用
SIAM JOURNAL ON MATRIX ANALYSIS AND APPLICATIONS 1999年 第4期20卷 1083-1098页
作者: Geist, GA Howell, GW Watkins, DS Oak Ridge Natl Lab Math Sci Sect Oak Ridge TN 37831 USA Florida Inst Technol Dept Appl Math Melbourne FL 32901 USA Washington State Univ Dept Pure & Appl Math Pullman WA 99164 USA
The BR algorithm, a new method for calculating the eigenvalues of an upper Hessenberg matrix, is introduced. It is a bulge-chasing algorithm like the qr algorithm, but, unlike the qr algorithm, it is well adapted to c... 详细信息
