This thesis is focussed on the regularization of large-scale linear discrete ill-posed problems. Problems of this kind arise in a variety of applications, and, in a continuous setting, they are often formulated as Fredholm integral equations of the first kind, with smooth kernel, modeling an inverse problem (i.e., the unknown of these equations is the cause of an observed effect). Upon discretization, linear systems whose coefficient matrix is ill-conditioned and whose right-hand side vector is affected by some perturbations (noise) must be solved. %Because of the ill-conditioning of the system matrix and the errors in the data, In this setting, a straightforward solution of the available linear system is meaningless because the computed s...
