Recursively defined interpolation nodes for the simplex
pip install recursivenodes==0.1.0
recursivenodes: Recursive, parameter-free, explicitly defined interpolation nodes for simplices
This package includes one module level function,
recursive_nodes(), which returns
nodes for polynomial interpolation on the simplex in arbitrary dimensions.
The nodes have a few nice properties: they are explicitly constructed and fully symmetric, and their traces on edges are Lobatto-Gauss-Legendre nodes (or any other node set you wish to use). Among explicitly constructed nodes, they appear to have the best interpolation properties. You can find more details in the documentation.
