I appreciate any tip on how to implement these two finite elements.
Diego -- these are difficult to implement as far as I know. I can't find this from the pages you link to, but my understanding is that for these elements, one needs not only ensure continuity of the solution across interfaces between cells, but also continuity of the derivative. Is that right?
