To cite MetricGraph in publications use the first of the following references to cite the package. If you use the Whittle--Matérn models (for example if you use graph_spde in 'INLA' or 'inlabru'), please cite references 2,4 and 5, and if you use the fractional Whittle--Matérn models with FEM approximations, please cite references 2 and 3.
