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?

在 MATLAB Online 中打开

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.
