Fs=10
t=0:1/Fs:1
x1=cos(2*pi*t*3)+cos(2*pi*t*4)+cos(2*pi*t*8)+cos(2*pi*t*10)
fft_x1=fft(x1)
fft_shift=fftshift(fft_x1)
mag=abs(fft_shift)
N=length(t)
f=-Fs/2:Fs/N:Fs/2-(Fs/N)
stem(f,mag)
fr=[]
for k=1:N
sum=0
for n=1:N
out=x1(n)*exp((-i*pi*2*n*k)/N)
sum=sum+out
end
fr=[fr sum]
end
fr=fftshift(fr)
mag1=abs(fr)
plot(t,x1)
title('signal time')
stem(f,mag1)
for this code matlab is hanging ,but for other programs matlab is working fine what is the problem in the code

It doesn't hang for me.
But you should not use the name "sum" for your variable since it's the name of a very important built-in function that you will overwrite.

You can clear followed by the name of the function.
Exception: if what you overwrote was clear itself, then
builtin('clear', 'clear')
If you ovewrote builtin and clear then you need the special behaviour
builtin clear clear
This will, as a special case, not invoke
builtin('clear', 'clear')
where builtin in the above line refers to whatever you overwrote builtin with.

Doesn't seem to be hanging for me!
Where are you having problem? Have you tried running in Debug mode?
