Condition number of Bott–Duffin inverse and their condition numbers

Applied Mathematics and Computation, 2003
The paper studies the normwise relative condition number of the Bott-Duffin inverse and the corresponding condition number for the constrained linear systems \(Ax+y=b,x\in L,y\in L^{\bot }\). Since the condition number cannot be computed exactly, the authors consider the sensitivity of the problem ``the condition number of the condition number'' by ...

Norms, Condition Numbers

2016
In the following chapter we are going to discuss the solution of a system of linear equations $$\displaystyle{ Ax = b }$$ (2.1) where A is an n × n real matrix: \(A \in \mathbb{R}^{n\times n},\,b \in \mathbb{R}^{n}\) is a given vector and \(x \in \mathbb{R}^{n}\) is the unknown vector.
