چکیده

We present a fast and numerically stable algorithm for computing the eigendecom-position of a symmetric block diagonal plus semiseparable matrix. We report numerical experiments that indicate that our algorithm is signiicantly faster than the standard method which treats the given matrix as a general symmetric dense matrix.

Superfast Divide-and-Conquer Method and Perturbation Analysis for Structured Eigenvalue Solutions

We present a superfast divide-and-conquer method for finding all the eigenvalues as well as all the eigenvectors (in a structured form) of a class of symmetric matrices with off-diagonal ranks or numerical ranks bounded by r, as well as the approximation accuracy of the eigenvalues due to off-diagonal compression. More specifically, the complexity is O(r2n logn) + O(rn log n), where n is the or...

Free Vibration Analysis of Repetitive Structures using Decomposition, and Divide-Conquer Methods

This paper consists of three sections. In the first section an efficient method is used for decomposition of the canonical matrices associated with repetitive structures. to this end, cylindrical coordinate system, as well as a special numbering scheme were employed. In the second section, divide and conquer method have been used for eigensolution of these structures, where the matrices are in ...

Homotopy algorithm for the symmetric diagonal-plus-semiseparable eigenvalue problem

A dense symmetric matrix can be reduced into a similar diagonalplus-semiseparable one by means of orthogonal similarity transformations. This makes such a diagonal-plus-semiseparable representation a good alternative to the tridiagonal one when solving dense linear algebra problems. For symmetric tridiagonal matrices there have been developed different homotopy eigensolvers. We present a homoto...

An Orthogonal Similarity Reduction of a Matrix into Semiseparable Form

An orthogonal similarity reduction of a matrix to semiseparable form. Abstract It is well known how any symmetric matrix can be reduced by an orthogonal similarity transformation into tridiagonal form. Once the tridiagonal matrix has been computed, several algorithms can be used to compute either the whole spectrum or part of it. In this paper, we propose an algorithm to reduce any symmetric ma...

A Levinson-like algorithm for symmetric positive definite semiseparable plus diagonal matrices

In this paper a Levinson-like algorithm is derived for solving symmetric positive definite semiseparable plus diagonal systems of equations. In a first part we solve a Yule-Walker-like system of equations. Based on this O(n) solver an algorithm for a general right-hand side is derived. The new method has a linear complexity and takes 19n − 13 operations. The relation between the algorithm and a...
