could be a
triangulationreturned bytriangulateor a named list containing:nodes, a #nodes-by-2 matrix containing the x and y coordinates of the mesh nodes;elements, a #elements-by-3 matrix specifiying the triangles giving the row's indices innodesof the triangles' vertices;boundary, a #nodes-by-1 matrix, with entries either '1' or '0'. An entry '1' indicates that the corresponding node is a boundary node; an entry '0' indicates that the corresponding node is not a boundary node.
