Implicit residual type error estimators
(Springer, 2016)
Capítol de llibre
Accés restringit per política de l'editorialThe error associated with a numerical solution is intimately related with the residual, that is the lack of verification of the equation by the approximated solution. The residual is computable but obtaining the exact ... -
