On the iterative solution of systems of the form $A^{T}Ax=A^{T}b+c$

Henri Calandra, Serge Gratton, Elisa Riccietti +1

Given a full column rank matrix $A\in {\mathbb{R}}^{m\times n}$ ($m\ge n$), we consider a special class of linear systems of the form $A^{\top }Ax=A^{\top }b+c$ with $x, c \in \mathbb{…
