Anisotropic weights for RBF-PU interpolation with subdomains of variable shapes
R. Cavoretto, A. De Rossi, G. E. Fasshauer +2
The partition of unity (PU) method, performed with local radial basis function (RBF) approximants, has already been proved to be an effective tool for solving interpolation or coll…
