形形色色的插值法中,有这样一种插值方法,人们称之为样条插值(spline interpolation)—— 这时候,有的小朋友想要抢答了:我知道我知道,就是三次样条插值嘛!—— 我曾经也是想当然的以为,“样条插值”就是满足某种特殊条件的三次插值,虽然认识到这仅仅是基于对一元函数插值的片面理解,但还是会以为从一元函数到二元函数...

cubic spline interpolation 概念解释和实现 博客参考:https://blog.csdn.net/flyingleo1981/article/details/53008931 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,并附C语言的实现代码。
2. 双线性插值(Bilinear Interpolation)在数学上,双线性插值是有两个变量的插值函数的线性插值扩展,其核心思想是在两个方向分别进行一次线性插值。 图中:红色的数据点与待插值得到的绿色点假如我们想得到未知函数 f 在点 P = (x, y) 的值,假设我们已知函数 f 在 Q11 = (x1, y1)、Q12 = (x1, y2), ...
Therefore, to force interpolation it is more desirable to introduce multiple knots than multiple control points. Exercises 1. Show that translating each control point of a B-spline curve by a vector v translates the entire B-spline curve by v. 2. Let S(t) be a B-spline curve with ...

General Spline Interpolation If you want to interpolate at sites other than the breaks and/or by splines other than cubic splines with simpleknots, then you use thespapicommand. In its simplest form, you would saysp = spapi(k,x,y); in which the first argument,k, specifies theorderof ...
