这是我直接画的原始数据(未作拟合):

但是我看不出这些曲线有什么规律可以拟合.
请您明确说一下怎么个拟合法,用什么函数拟合;还是说只是要做插值,插成什么样.

(急)用matlab拟合并求曲线方程!有一条B样条曲线 收集了它每间隔一小段的坐标 用什么函数拟合最佳?怎么求出拟合出的曲线方程? 我用matlab做了两条离散点的拟合曲线,现在相求这两条线的交点,用什么程序 matlab 如何拟合二维函数表达式? z=f(x,y)就像matlab里用“lsqcurvefit”拟合一维函数y=f(x)一样,不同的是未知数有两个.比如,已知函数表达式是 z=a0+a1*x+a2*y并且已知三组数据,(比如可以用z=3x+4 用matlab拟合下面一组数据的曲线x=[-2.30259,-1.60944,-1.20397,-0.91629,-0.69315,-0.51083,-0.35667,-0.22314,-0.10536,0.00000,0.40546,0.69315,0.91629,1.09861,1.25276,1.38629,1.50408,1.60944,1.70475,1.79176];y=[2.48491,3.06805,3.21888,3.31419, 怎么用matlab画拟合曲线已知一组数据如何画拟合曲线,并且将拟合曲线与原曲线同时画在一张图上这个问题我自己有答案,只是为了完成任务提的.拟合曲线的算法是用a=plotfit(xdat,ydat,n)其中n Matlab中拟合三维曲线,并且不知道这条曲线的方程.matlab或其他数据拟合的工具,如果有三个变量X、Y、Z,对应每一个X,都能得到一个Y和Z的值,对于我得到的这些三维数据,能够得到一条空间曲线,
