(anonymousFunction) aFittype=fittype(anonymousFunction,Name,Value) fit()函数语法: fitobject=fit(x,y,fitType) fitobject=fit([x,y],z,fitType) fitobject=fit(x,y,fitType,fitOptions) fitobject=fit(x,y,fitType,Name,Value) [fitobject,gof]=fit(x,y,fitType) [fitobject,gof,output]=fit(x,y,...
You can create different variants or customized versions of the same function with anonymous functions or nested functions. For example, if we want to create a function like y = ax2+ bx + c and customizea,b, orcat runtime, we write a=3; b=2; c=-10; y1=@(x) a*x...
除主函数(main function)外,还有局部函数(Local functions),它定义在M函数文件里的除第一个位置外的地方(所以,它只能依附在主函数文件中,不能出现在M脚本文件中),它只在该文件内可见,下面是一个例子(取自Matlab R2014帮助文档“Local Functions”,文件“mystats.m”): 1 function [avg, med] = mystats(x)...
Matlab的函数以M函数文件(后缀.m)形式存在,主函数(Main Function,这里主函数和C语言主函数不同,它指该函数文件中第一个定义的函数,可以理解为文件的对外接口)名要和文件名相同,一个主函数的例子如下(文件“rank.m”,位于“C:\Program Files\MATLAB\R2014a\toolbox\matlab\matfun\”): 1 function r = rank...
Pn is the taylor polynomial of the degree (at most) n centred at x0=0 for the function cos(x) The function should take inputs a and n and return Pn evaluated at x=a 테마복사 function Pn = taylor_cos(a,n) x=a; Pn=1; for i=...
forii=1:numel(hf) options = optimoptions('fsolve','Display','none','PlotFcn',@optimplotfirstorderopt); neff = [0; 5]; NEFF(ii)=fsolve(@(hf) eff(hf(ii), neff), neff,options); end %plot(hf, NEFF) functionF = eff(hf, neff) ...

Matlab是为矢量和矩阵操作而设计的,因此,可以通过矢量化方法加速M文件的运行。矢量化是指将for循环和while循环转换为等价的矢量或矩阵操作。下面给出一个循环的例子: i=0; for n = 0:0.1:1000 i=i+1; y(i)=cos(n); end 那么我们可以矢量化为: ...
Sean, are you including a trailing semi-colon for the anonymous function definition? And are you keeping to the requirement that the created function be named "until" and that it must take an argument and that argument must be named "n" ?It...
上面文件首行以function开头的称为函数声明行(function declaration line),紧接一行注释称为H1行(用作lookfor指令),H1行及之后的连续注释称为在线帮助文本(help text,用作help指令),再之后的注释称为编写和修改记录(上面例子中没有,用作软件归档管理),之后是函数体。当然,除函数声明和函数体外其他都是可选的。
