| Post subject: | RBF for 3D points |
Im trying to use RBF interpolation to model a variable U = f(x,y,z), where U is a scalar value, and (x,y,z) belongs to a set of 3D points. If I understand correctly such model can be creatd as follows: alglib.rbfmodel Umodel; alglib.rbfcreate(3, 1, out Umodel); However, I don't know how to add the data set, since the function alglib.rbfsetpoints(Umodel, dataset); only seems to supports a bi-dimensional array for dataset. Best regards, Roberto Aguirre Maturana La Serena, Chile. |
