MATLAB测定薄膜透射率的数学模型

主要求解过程：

执行过程：

tdata = linspace(100,1000,10);
cdata = 1e-05.*[454 499 535 565 590 610 626 639 650 659];
x0 = [0.2,0.05,0.05];
x  = lsqcurvefit('curvefun',x0,tdata,cdata)
f = curvefun(x,tdata)

plot(tdata,cdata,'o',tdata,f,'r-')

函数文件curvefun.m

function f = curvefun(x,tdata)
f = x(1)+x(2)*exp(-0.02*x(3)*tdata);

结果：
