Create a Knot Sequence and Plot the B-spline, This figure shows a B-spline of order 4 and the four cubic polynomials that composes it. To replicate this figure in MATLAB , first create a knot sequence. A knot sequence must be non-decreasing. t 0 1.5 2.3 4 5; As you have defined five knots, the B-spline will be of order 4. Your function called, bsplinebasis() calls a nested function called, bsplinebasisrecurrence() and the nested function again calls the parent function bsplinebasis(). You cannot do this because you are basically calling the same function inside itself which (in some cases) results in an infinite loop.

The number of points per interval (default 10) and the order of the B-spline (default 3) can be changed. Periodic boundaries can be used. It works on any dimension (even larger than 3.). This code is inspired from that of Stefan Hueeber and Jonas Ballani 1. This function performs Cubic B-spline interpolation on XY range data. You should specify the X coordinates on the spline, and it will output a vector contains the interpolated Y values on these X values. Examples. 1.

The nuclear reaction data from the file carbon12alpha.mat is shown here with three smoothing spline fits. The default smoothing parameter (p 0.99) produces the smoothest curve.The cubic spline curve (p 1) goes through all the data points, but is not quite as smooth.The third curve (p 0.95) misses the data by a wide margin and illustrates how small the "interesting range" of p can be.

The B-spline is piecewise polynomial of order k, i.e., its polynomial pieces all are of degree < k. For k 14, you can even observe that all its nonzero polynomial pieces are of exact degree k - 1, by looking at the first three derivatives of the B-spline. This means that the degree goes updown by 1 every time you adddelete a knot.
