International audience; The main result of this paper is the formulation of an explicit expression for the condition number of the truncated least squares solution of $Ax=b$. This expression is given in terms of the singular values of $A$ and the Fou

We present an explicit expression for the condition number of the truncated total least squares (TLS) solution of $Ax \approx b$. This expression is obtained using the notion of the Frechet derivative. We also give upper bounds on the condition numbe

International audience; The method of conjugate gradients (CG) is widely used for the iterative solution of large sparse systems of equations $Ax=b$, where $A\in\Re^{n\times n}$ is symmetric positive definite. Let $x_k$ denote the $k$th iterate of CG
