[MATLAB基础] 求高手帮忙查个小错

[alee817]

clear;clc;
x=[-150 -100 -50 0 50 70 100 150 200 250];
y=[0 0.01 0.28 0.56 0.78 0.8 0.65 0.45 0.1 0];
myfunc=inline('0.98*0.1683*exp(sqrt(pi)*x*beta(1)/321.9)-exp(sqrt(pi)*beta(2)/279.3*(x-(200-beta(3)-beta(4))*sin(beta(5)+10)/sin(beta(5))))','beta','x');
beta=nlinfit(x,y,myfunc,[2 2 15 15 30]);
j=beta(1),k=beta(2),s1=beta(3),s2=beta(4),p=beta(5)
%test the model
xx=min(x):max(x);
yy=0.98*0.1683*exp(sqrt(pi)*x*j/321.9)-exp(sqrt(pi)*k/279.3*(x-(200-s1-s2))*sin(p+10)/sin(p)));
plot(x,y,'o',x,yy,'r')

运行时告诉我缺失符号。
