Artículo de publicación ISIIn this paper we provide some Matlab tools for efficient vectorized coding of the Hybridizable Discontinuous Galerkin for linear variable coencient reaction-discusion problems in polyhedral domains. The resulting tools are modular and include enhanced structures to deal with convection-discusion problems, plus several projections and a superconvergent postprocess of the solution. Loops over the elements are exclusively local and, as such, have been parallelized.
