hold on
plot(Ct,-Vs,'r-',Ct,-Vs1,'g');
xlabel("C_t");
ylabel("V_s");
title("Descent Rate vs. Thrust Coefficient");
legend({'Normal Diameter','Diameter x 1.25'},'FontSize',12,'Location','northeast','Orientation','horizontal')
figure(2)
plot(Ct,Cd_eq,'r-',Ct,-V_autorotationaldescent,'b')
xlabel('C_t')
ylabel('Cd_eq')
addaxislabel(2,'steady autorotational descent')
legend({'Cd_(eq)','V_s/\OmegaR'},'FontSize',14,'Location','northeast','Orientation','horizontal')
hold off
% sir i got the plot no.1 with legend and axis name and all.
% having problem in figure 2 not getting lengend and not getting 2 y axis
% name, help sir

Well, it is not part of MATLAB itself, so to use it in MATLAB you need to install addaxislabel from somewhere such as the File Exchange contribution I linked to.
