If I generate a fit wth the FIT function, I am then unable to use that object as a normal function. Sure you can. x=1:5; y=x.^2; f=fit(x(:),y(:),'poly2') f = Linear model Poly2: f(x) = p1*x^2 + p2*x + p3 Coefficients (with 95% confidence bounds): p1 = 1...
function fitness=fit(len,m,maxlen,minlen) fitness=len; for i=1:length(len) fitness(i,1)=(1-((len(i,1)-minlen)/(maxlen-minlen+0.0001))).^m;% end 遗传算法-免疫遗传函数 function a=immuni(a,b) m=length(a); c=zeros(m); for i=1:m c(i)=a(i); c(i+1)=a(b(i,2)); ...
(1)只显示拟合图像,可以点击 文件-Print to figure (2)导出拟合后的曲线数据,点击 文件-generate code 1.产生一个createFit1的函数,如下图所示 具体介绍就是函数名为createFit,输入参数为x、y,输出参数为fitresult 和gof. 其中fitresult 包含求解系数,gof代表拟合评价。
这个过程大多数读者应该都有了解,问题在于:“how to get fit data”?首先我们需要先把函数工具拟合方法生成代形式: 代码语言:javascript 代码运行次数:0 运行 AI代码解释 function [fitresult, gof] = createFit(x1, y1) %CREATEFIT(X1,Y1) % Create a fit. % % Data for 'untitled fit 1' fit: % X...
matlab fitcknn函数用法 matlab的fit函数 plotfit函数使用 plot是画图函数 polyval是求值函数 polyfit是曲线拟合函数 polyfit用于多项式曲线拟合 p=polyfit(x,y,m) 其中, x, y为已知数据点向量, 分别表示横,纵坐标, m为拟合多项式的次数, 结果返回m次拟合多项式系数, 从高次到低次存放在向量p中....

Fit computation did not converge:拟合计算未收敛: Fitting stopped because the number of iterations or function evaluations exceeded the specified maximum.拟合停止,因为迭代次数或函数求值次数超过了指定的最大值。 说明拟合参数xm和r的初始值设置有问题,这就需要我们更改拟合参数xm和r的值,我们可以一个个数去试...
