Upload your code(just the legend part)

[areej abdulshaheed]

s0=[zeros(1,9) 1 zeros(1,34)]

tspan=(0:0.1:50);

options=odeset('absTol',[1e-10]);

[t,s]=ode15s(@matg,tspan,s0,options);

Q1=s(:,1); Q2=s(:,2); Q3=s(:,3);

Q4=s(:,4); Q7=s(:,7);

subplot 221

plot(t,Q1,'--',t,Q4,'.-',t,Q7)

xlabel('time'), ylabel('joint angle [rad]')

legend('\phi1','\phi4','\phi7')
