I D[(X2,Y2},t]/.t+O WebThe above definitions for B-spline curves are then rewritten as vectors and tensors to create a 3D parametric B-spline representation of multivariate data. This is the type of approach used in multivariate statistics and machine learning, and such an approach can be implemented in R, MATLAB, Mathematica, and other analysis software. WebBy default, BSplineFunction gives cubic splines. The option setting SplineDegree-> d specifies that the underlying polynomial basis should have maximal degree d. By default, knots are chosen uniformly in parameter space, with additional knots added so that the curve starts at the first control point and ends at the last one. swarthout canyon rd san bernardino
