Abstract
Regularization methods for applied inverse and ill-posed problems have received considerable attention (see e.g. [1, 2]). We shall be concerned here with determining the optimal regularization parameter required for the solution of the discrete ill-posed problem Aø H = ø B , which arises in electrocardiography when one seeks to recover epicardial potentials ø H from body-surface potentials ø B via a transfer-coefficient matrix A [3, 4]. In saying that the problem is ill-posed, we mean that the matrix A is ill-conditioned, with singular values decaying to zero in such a way that no practical separation point can be identified in the singular value spectrum of A.
