求助！Function definitions are not permitted at the prompt or in scripts

function xdot = lorenzeq(t,x)
xdot=[-8/3*x(1)+x(2)*x(3);
-10*x(2)+10*x(3);
-x(1)*x(2)+28*x(2)-x(3)];
t_final=100; x0=[0;0;1e-10];
[t,x]=ode45('lorenzeq',[0,t_final],x0);
plot(t,x),
figure; plot3(x(:,1),x(:,2),x(:,3)); axis([10 40 -20 20 -20 20]);
为什么每次运行之后都说出现错误呢？
??? function xdot = lorenzeq(t,x)
