Honey bees (Apis melliferaL) suffer from many brood pathogens, including viruses. Despite considerable research, the molecular responses and dynamics of honey bee pupae to viral pathogens remain poorly understood. Israeli Acute Paralysis Virus (IAPV)

In this paper, we are interested in computing the solution of an overdetermined sparse linear least squares problem Ax=b via the normal equations method. Transforming the normal equations using the L factor from a rectangular LU decomposition of A us

On cache based computer architectures using current standard algorithms, Householder bidiagonalization requires a significant portion of the execution time for computing matrix singular values and vectors. In this paper we reorganize the sequence of

International audience; We investigate how to use an LU factorization with the classical LSQR routine for solving overdetermined sparse least squares problems. Usually L is much better conditioned than A and iterating with L instead of A results in f

BHESS uses Gaussian similarity transformations to reduce a general real square matrix to similar upper Hessenberg form. Multipliers are bounded in root mean square by a user-supplied parameter. If the input matrix is not highly nonnormal and the user

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 computing the eigenvalues of the n

Recently, Geist has given an algorithm to find eigenvalues of a general matrix by tridiagonalization, followed by L lower triangular, R upper triangle (LR) iteration. The total computational cost is 4 3 n 3 + O(n 2 ) flops. This paper shows how to mo
