未定义与 'inline' 类型的输入参数相对应的函数 'nlinfit'。

求高手看下怎么改
x = [2,3,4,5,7,8,10,11,14,15,15,18,19];
y = [106.42,109.20,109.58,109.50,110.00,109.93,110.49,110.59,110.60,110.90,110.76,111.00,111.20];
myfunc = inline('beta(1)+beta(2).*log(x)','beta','x');
beta0 = [0.2,0.2];
beta = nlinfit(x,y,myfunc,beta0);

估计是你的版本的问题。20a版能正常运行,算出来
beta = 106.711310208455 1.56634344771415
