Query: MATLAB Implementation of C1 finite elements: Bogner-Fox-Schmit rectangle   Rahman and Valdman (2013) introduced a new vectorized way to assemble finite
element matrices. We utilize underlying vectorization concepts and extend
MATLAB codes to implementation of Bogner-Fox-Schmit C1 rectangular elements in
2D. Our focus is on the detailed construction of elements and simple computer
demonstrations including energies evaluations and their visualizations.
