Approximate low-rank factorization with structured factors

, 2010
An approximate rank revealing factorization problem with structure constraints on the normalized factors is considered. Examples of structure, motivated by an application in microarray data analysis, are sparsity, nonnegativity, periodicity, and ...

Modifying a Sparse Cholesky Factorization

, 1999
Given a sparse symmetric positive de nite matrix AA and an associated sparse Cholesky factorization LDL , we develop sparse techniques for obtaining the new factorization associated with either adding a column to A or deleting a column from A ...

Bidiagonal Factorization

, 2011
This chapter introduces and methodically develops the important and useful topic of bidiagonal factorization. Factorization of matrices is one of the most important topics in matrix theory, and plays a central role in many related applied areas such as numerical analysis and statistics. Investigating when a class of matrices admits a particular type of

Successively Ordered Elementary Bidiagonal Factorization

SIAM Journal on Matrix Analysis and Applications, 2001
Let \(I\) be the identity matrix and \(E_{ij}\) the matrix with \((i,j)\)-entry \(1\) and zeros in all other positions. Define \(L_i(s)=I+sE_{i,i-1}\) and \(U_j(t)=I+tE_{j-1,j},\) where \(s,t\) are elements in a given field \(F.\) The matrices \(L_i(s)\) and \(U_j(t)\) are called elementary bidiagonal matrices. The authors give necessary and sufficient
