Global basis function

WebNov 1, 2024 · There are two main groups of basis functions: global RBFs and compactly supported RBFs (CS-RBFs) [8]. Fitting scattered data with CS-RBFs leads to a simpler and faster computation, because a system of linear equations has a sparse matrix. However, approximation using CS-RBFs is quite sensitive to the density of approximated scattered … http://twister.caps.ou.edu/CFD2024/Chapter7.pdf
