This MATLAB function returns the spline f (if any) of order k = length(knots) - length(x) with knot sequence knots for which (*) f(x(j)) = y(:,j), all j.
This step shows how to apply 'natural' cubic spline interpolation to the function f2(x)=((x−2)+)3, and plot the error. The code below computes the 'natural' spline interpolant with an alternative argument syntax that is equivalent to the 'variational' argument: using 'second' specifies...

Cubic Spline Interpolation Copy Code Copy CommandThis example shows how to use the csapi and csape commands from Curve Fitting Toolbox™ to construct cubic spline interpolants. The CSAPI Command The command values = csapi(x,y,xx) returns the values at xx of the cubic spline interpolant to...
I am not sure if this is the correct way of using the Cubic spline interpolation function but I used spline(x,y,33) and got ans = 24.3906. Shouldn't I still get the same value for f(33) no matter what type of interpolation I use? matlab interpolation cubic-spline Share Follow ...
三次样条插值（CubicSplineInterpolation）及代码实现（C语言）三次样条插值（CubicSplineInterpolation）及代码实现（C语 ⾔）样条插值是⼀种⼯业设计中常⽤的、得到平滑曲线的⼀种插值⽅法，三次样条⼜是其中⽤的较为⼴泛的⼀种。本篇介绍⼒求⽤容易理解的⽅式，介绍⼀下三次样条插值的原理，...
I understand you want to know about cubic interpolation methods "makima", "spline" and "pchip" and differences between them. Please run the following command- ThemeCopy >> openExample('matlab/DataInterpolationComparisonExample') This command will open the example "Data Interpolation with spline, pc...
I'm trying to write a cubic spline interpolation program. I have written the program but, the graph is not coming out correctly. The spline uses natural boundary conditions(second dervative at start/end node are 0). The code is in Matlab and is shown below, clear all %Function to Inter...
