Abstract

This paper deals with regularization and noise level control of source depending only on the spatial variable in the heat equation. In this problem, the Krylov method is employed to get the regularization solution and control noise level in case perturbation. Various numerical tests are given to verify the efficiency of the proposed method and until what point the method resist at the perturbations
