介绍利用matlab中surface fitting tool这个工具箱来进行曲面拟合的一个过程。 第一步:在matlab中输入指令sftool打开这个工具箱,会得到如下的页面 在页面的左上角分别是一些工具栏,比如保存文件、新建文件还有一些其他的工具,如插入格网、插入标注等,我也没有全部仔细看过。在工具栏下面是一些功能图标,如显示等高线,...
matlab_surface_ fitting_tool图像导出 第一步生成图像 第二步保存你和数据到workspace 第三步在workspace中绘制 拟合的图形就会出现到figure中了。

一般情况下matlab会直接提供常用的类型,用fittype创建拟合模型。至于matlab具体提供了哪些模型,参见帮助"List of library models for curve and surface fitting" ft = fittype('gauss1'); %高斯拟合 如果库中没有自己想要的拟合形式,可以自己进行定义,此时使用匿名函数是很方便的,格式如下 ...

分享一下使用非线性函数对数据进行拟合。非线性函数假定是标准指数衰减曲线, y(t)=Aexp(−λt) 其中,y(t) 是时间 t 时的响应,A 和λ 是要拟合的参数。对曲线进行拟合是指找出能够使误差平方和最小化的参数 A 和λ,误差平方和为目标函数 创建样本数据 ...
