how to plot different graphs for each iteration of a for loop?

t=linspace(0,12,1000);
T=2;
Y=g(t)';
f=0;
N=50;
hold on;
h=zeros(N,1);
clr=lines(N);
for n=1:25:N;
    line(t,Y,'linewidth',5)
    grid on;hold on;
    A=(1/T)*quadgk(@g,0,T);
    P=@(t)g(t).*(cos(n*pi*t));
    Q=@(t)g(t).*(sin(n*pi*t));
    Ax=(2/T)*quadgk(P,0,T);
    Bx=(2/T)*quadgk(Q,0,T);
    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')).
I wish to plot different graphs for every iteration done. Is it poosible?

Put the "figure" command at the start of the for loop.

doc figure

for details.

Also, in the line

A=(1/T)*quadgk(@g,0,T);

you don't want the "@". It should be just

A=(1/T)*quadgk(g,0,T);

thanks Sir. Though I have already applied what you said but still I wish to know what is the difference between g & @g here.

It's easy to get confused on this. What quadgk() requires as its first argument is a function handle. So, for example, if you wanted to integrate the sine function, you would use

@sin

because that is the handle to the sine function. However, you have defined g yourself, and g is itself a function handle.

See this documentation page for details.
