WebOriginally, spline was a term for elastic rulers that were bent to pass through a number of predefined points, or knots. These were used to make technical drawings for shipbuilding and construction by hand, as illustrated in the figure. We wish to model similar kinds of curves using a set of mathematical equations. WebThis function computes a cubic spline or sub-spline s which interpolates the (xi,yi) points, ie, we have s (xi)=yi for all i=1,..,n. The resulting spline s is completely defined by the triplet (x,y,d) where d is the vector with the derivatives at the xi: s' (xi)=di (this is called the Hermite form). The evaluation of the spline at some points ...

WebThis is, more precisely, the cubic spline interpolant with the not-a-knot end conditions, meaning that it is the unique piecewise cubic polynomial with two continuous derivatives with breaks at all interior data sites except for the leftmost and the rightmost one. It is the same interpolant as produced by the MATLAB ® spline command, spline (x,y).

Web10 Feb 2024 · A cubic spline is a nonlinear function constructed of multiple third-order polynomials. These polynomials pass through a set of control points and have continuous first and second derivatives everywhere. The second derivative is set to zero at the left and right endpoints, to provide a boundary condition to complete the system of equations.
