Error Analysis of Direct Methods of Matrix Inversion
We analyze the effect of the rounding errors made in the solution of the problem of inverting a matrix using vector and matr ix norms for a number of direct methods. Expand

Inverse Iteration, Ill-Conditioned Equations and Newton’s Method
Inverse iteration is one of the most widely used algorithms in practical linear algebra but an understanding of its main numerical properties has developed piecemeal over the last thirty years: aExpand

Error analysis of floating-point computation
This paper consists of two main sections. In the first the bounds are derived for the rounding errors made in the fundamental floating-point arithmetic operations. In the second, these results areExpand

Ill-conditioned eigensystems and the computation of the Jordan canonical form
The solution of the complete eigenvalue problem for a non-normal matrix A presents severe practical difficulties when A is defective or close to a defective matrix. Expand
