In the context of RBF interpolation, can cubic RBF lead to solution of singular system?

Rocha [1] claims that there is an example of cubic RBF giving singular system in Powell's book. But I did not find it there. In chapter 3 (p.30-31) of Hubbert's book [2], they claim it happens but...

What is the advantage of Meshfree Methods over Finite Element / FInite difference method?

MeshFree methods take more time and provide similar accuracy (sometimes less) as the Finite Difference method?? ( Turned out, it's not true in general. RBF collocation are faster as pointed out by...
