Maybe you have some attempts? What did you try?

[manvi agarwal]

function bc()

tspan=[0 10];

IC=[1 1];

[T,X] = ode45(@(t,x) eq1(t,x),tspan,IC);

plot(T,X(:,2))

hold

plot(T,X(:,1))

end

function dx=eq1(t,x)

dx=zeros(2,1);

k=x(2);

sat=@(k) min(max(k,-1),1)

x(2)=k;

dx(1)=x(1)-x(2)

dx(2)=-x(1)-2*x(2)+1

end
