function x=signal(f,fs,N)
% sinusoid
f=30; %frequency,
N=10; %number of samples
fs=100; %sampling frequency
A=2; %amplitute
Total sampling time = 1 second
n = 0:N-1; % numbering the samples
x = A*sin(2*pi*f*n/fs);
plot(x)
MFx = abs(fft(x));
frek=(0:N/2-1)*fs/N;
plot(frek,MFx(1:N/2))% plot the positive frequencies
please help me.
thank you

You need to tell us how you are running the program, and you need to show the complete error message.

Kuehli, now you've been asked three times to show what you did. What arguments you supplied and how you ran it. Did you overlook the two comments up at the top? Why did you not answer them? Why don't you want to make it easy to help you instead of hard or impossible?

Kuheli, the attached m-file (below the plot) runs perfectly fine. It runs via the green run triangle, and it runs via typing F5. AND it runs with no errors at all and makes the plot below. It's all in one m-file, text3.m and is attached. If you can't run it, let me know, otherwise you can Accept this answer.
