Dubiner-sherwin-karniadakis polynomial basis
Usage
space Vh(omega,"S5");
Overview
This basis is described for the triangle by Dubiner (J. Sci. Comput., 1991) and extended by Sherwin and Karniadakis (2005, Cambridge Univ. Press) to others reference elements. It is indicated in the space (see space(2)) by a string starting with the letter "S", followed by digits indicating the polynomial order.
Options
This basis recognizes the equispaced/warburton node option for degrees of freedom located on sides. See basis_option(2).
