Bivariate basis functions
WebDownload scientific diagram A bivariate, cubic B-spline constructed from the basis functions in Fig. 4 and the coefficients c = 125, where 125 ∈ R 25 is a vector of 5 × 5 =25 ones. Webmatically appealing functions in their own right, it is the lin-ear combinations of such splines that are of main interest in modeling and/or data-fitting applications. Thus, the funda-mental question is how one can choose appropriate collec-tions of knot-setsto construct meaningful spaces spanned by bivariate B-splines.
