Custom Models - MATLAB & Simulin

  1. Supply a custom model to the fit function in the fitType input argument. You can use a MATLAB expression (including any .m file), a cell array of linear model terms, or an anonymous function. Create a fittype object with the fittype function to use as an input argument for the fit function
  2. (abs (Y-0.5)); F05 = 2*abs (x (b))
  3. Secondly, Matlab cannot process so many unknown parameters, a short one is OK, like this: ft = fittype(@(a,b,c,x1,x2) a*(x1.^b).*(x2.^c), 'independent',{'x1','x2'},'dependent',{'y'},'problem',{'b','c'})

f = fittype ('a*x^2+b*exp (n*x)'); category (f) ans = custom type (f) ans = customnonlinear g = fittype ('fourier4'); category (g) ans = library type (g) ans = fourier4. Introduced in R2006b. ×.

Fittype = fittype (expression) 使用如上两种方式,可以使用MATLAB已经实现的拟合算法或者使用自定义的拟合算法(可以引用.m文件),具体算法有'poly11','poly2','linearinterp'等,具体详见fittype的文档说明。. Fittype = fittype (expression,Name,Value) constructs the fit type with additional options specified by one or more Name,Value pair arguments. 这是常用公式,使用如下. g = fittype. Fit type for curve and surface fitting.
