“…For certain pathologies, one should solve the Cauchy problem hundreds or thousands of times in order to obtain the dynamics of the electrical information on the heart surface. In terms of computational cost, this reduces the competitiveness of the iterative methods like in [5], [15], [2], [20] and [26]) and gives more advantage for mesh-free methods like MFS ( [25]), where a transfer matrix is computed once for all. In this work we use the same energy function as defined in [5], but we formulate it at the continuous level using Dirichlet-Neumann and Neumann-Dirichlet mappings.…”

“…The transfer matrix was later computed using different approaches like boundary elements, finite elements or MFS. Recent works (Bouyssier et al [10]; Hariga et al [15]; Zemzemi, [26]; Zemzemi et al [27] ) presented novel approaches based on recent advances in boundary-value inverse problem techniques. These works use an energy-based cost function.…”
