for omega = 0:0.01:0.99999   
    xt=xo*cos(omegan*t)+((xodot)/(omegan))*sin(omegan*t)+ds*((cos(omega*t)-cos(omegan*t))/(1-(omega/omegan)^2));
    t=plot(t,xt);
    title(['\omega/\omega_n = ' num2str(omega) '/1'])
    saveas(gcf,num2str(omega),'jpg')
end

Undefined operator '*' for input arguments of type 'matlab.graphics.chart.primitive.Line'.

Error in forced (line 13)

xt=xo*cos(omegan*t)+((xodot)/(omegan))*sin(omegan*t)+ds*((cos(omega*t)-cos(omegan*t))/(1-(omega/omegan)^2));

The above error is being displayed while executing the above code. What is that error? how to rectify it?

The code is working fine when not in a loop.

You are using variable t as both numeric and graphics objects. Correct the second line of for loop

for omega = 0:0.01:0.99999   
    xt=xo*cos(omegan*t)+((xodot)/(omegan))*sin(omegan*t)+ds*((cos(omega*t)-cos(omegan*t))/(1-(omega/omegan)^2));
    T=plot(t,xt);
    title(['\omega/\omega_n = ' num2str(omega) '/1'])
    saveas(gcf,num2str(omega),'jpg')
end
