Matlab的拟合、优化和统计等工具箱常有下面几个名词: SSE(和方差、误差平方和):The sum of squares due to error MSE(均方差、方差):Mean squared error RMSE(均方根、标准差):Root mean squared error R-square(确定系数):Coefficient of determination Adjusted R-square:Degree-of-freedom […]
Matlab 2016要调用一个拟合好的函数非常简单: f = fittype(‘a*x^2+b*exp(n*x)’) %给出函数 f = General model: f(a,b,n,x) = a*x^2+b*exp(n*x) c = cfit(f,1,10.3,-1e2) %给出相应参数,返回函数值 c […]
