MATLAB: Having a system of three state I put the odes in a function and the script to solve the given function but now it is executing continuously, so tell me how to stop it

ode 45terminal sliding mode

function xdot=func4(t,x)
A=[0 1 0;0 0 1;-1 -2 -3]
B=[0 0;0 1;1 0]
C1=[0 1]'
C2=[1 0 ;0 1]
C3=[1 0]'
s=[C1*x(1)+C2*[x(2);x(3)]+C3*x(1)^(3/4)]
u1=[1;0]*x(1)+[1 3;0 -1]*[x(2);x(3)]-3/5*[0 0;1 0]*[x(2);x(3)]*x(1)^-2/5-[0 0.1;0.1 0]*(s/norm(s))
u2=[1;0]*x(1)+[2 2.9;-0.1 -1]*[x(2);x(3)]
u=u1+u2
xdot=A*x+B*u
%and by using ode 45
clc; clear all close all;
tspan=[0 8]
x0=[0.15;-0.15;0.1]
[t,x]=ode45('func4',tspan,x0)
plot(t,x(:,1),t,x(:,2),t,x(:,3))
now it is not stopping, it runing from last hours continuously
please check the code and suggest what to do?
