how can i extend my graph to 10 secs by replicating it??

t=[-1;-0.8;-0.6;-0.4;-0.2;0;0;0.2;0.4;0.6;0.8;0.8;1;];

Y=[-1;-1;-1;-1;-1;-1;1;1;1;1;1;-1;-1;]';

f=0;

N=10;

hold on;

h=zeros(N,1);

clr=lines(N);

for n=1:2:N;

    line(t,Y,'linewidth',5)

    grid on;hold on;

    A=0.5*trapz(t,Y);

    P=Y.*(cos(n*pi*t))';

    Q=Y.*(sin(n*pi*t))';

    Ax=trapz(t,P);

    Bx=trapz(t,Q);

    f=f+(Ax*cos(pi*n*t)+Bx*sin(pi*n*t));

    final=A+f;

    h(n)=plot(t,final,'linewidth',2,'Color',clr(n,:));

end

hold off;

legend(h, num2str((1:N)','harmonic-%d'))

Replicating the graph ??? Like with subplot() or axes() so that you have two graphs/plots/axes???? Or do you mean replicating your data (with repmat)? Or extending the t axis out to 10 with xlim)? Please clarify!

Sir, I meant extending the t axis out to 10 mins.

Did you try my suggestion of xlim()??? I imagine you must have by now , but it would look something like this:

xlim([-1, 10]);
