Bivariate basis functions
WebOne can consider the tensor product B-splines as a linear combination of the bivariate basis functions (for and ) which are bivariate polynomials of degree in and in defined as: (2. 104) Given the properties of the univariate B-spline basis functions, the basis function is non-zero only over the interval . WebJun 3, 2010 · In this paper, Radial Basis Function (RBF) method for interpolating two dimensional functions with localized features defined on irregular domain is presented. RBF points located inside the domain and on its boundary are chosen such that they are the image of conformally mapped points on concentric circles on a unit disk. On the disk, a …
