曲线拟合成Y=a*(X^b)+c*(X^d)函数
我知道Y=a*(X^b)形式的函数是幂函数 （power function），在Origin自带的函数库里有。
Origin8.0或更高的版本里，点击Origin菜单栏上的Analysis ——& Fitting ——& Nonlinear Curve Fit ——& Open Dialog，
在新弹出的拟合对话框中，右侧的 Category 选项中选择 Power，在 Function 选项中选择Allometric1 就是要的 y = a*( x ^b )
我的曲线数据如下：

现在我用 y = a*( x ^b )函数拟合效果不好，
所以我想把曲线你合成拟合成Y=a*(X^b)+c*(X^d)形式，其中Y，X为变量，a,b,c,d为常数，请问哪位高手知道在Origin里怎么实现，或者用matlab实现也可以，请帮助
如果更复杂些拟合成Y=a*(X^b)+c*(X^d)+e*(X^f)形式呢？
谢谢你介绍的软件，
我用 y = a*( x ^b )函数拟合的结果是

这个结果和Origin基本一样，但是你的结果最后6个点显然不好，所以打算用Y=a*(X^b)+c*(X^d)形式来拟合，你的拟合结果是很好，但是我要求系数a和c都要&0，-1/3&b和d&0,才有物理意义。
c，d拟合的结果最好就是和用 y = a*( x ^b )函数拟合的
a& && && & & & & & 4.82
b& && && & & & & & -1.37
相差不是太大，采用物理意义。
我试了一晚上，也没有满意的结果，难道只要 y = a*( x ^b )函数分段拟合吗？（把最后6个点分出来拟合？）但是这样又怎么用一个公式来表达这个曲线呢？
晕了，怎么贴图？

显然不是我想要的啊，我之前也设定了参数a,b,c,d的范围。如下：

d& && && & & & & & 0.661
参数b,d显然没有被分开，c的值与实际物理量比较接近，a值太小了，不符合实际物理意义啊，请高手继续指点，谢谢！
按照你说的
Function&&y = a*x^(-1/b)+c*x^(-1/d);
Function&&y = a*x^(-1/b)+c*x^(-1/(b+d));
计算结果中，a，d值都太小了，还是分不开啊

谢谢你的帮助，我要的是乘幂函数 y = a*x^(-1/b)+c*x^(-1/d);
因为只有这个公式才是我要解决的工程问题，不是指数函数，指数函数拟合的再好，不符合物理模型，也没啥用啊
