MATLAB: Discrete fourier transform by matlab

Question

I would like to program

x(n)={10, 9,1,5,0,8,4} this function to X(ω)

I wanna know magnitude ofㅣX(ω)ㅣrepresented in ω-domain plot

please answer me the code of this program and I will appreciate so much

if you show me the capture or figure of plot .

Answer 1

   x = [10 9 1 5 0 8 4];
   xdft = fft(x);
   plot(abs(xdft))

A better example would be something like:

    Fs = 1000;
    t = 0:1/Fs:1-1/Fs;
    x = cos(2*pi*100*t)+randn(size(t));
    xdft = fft(x);
    freq = 0:Fs/length(x):Fs/2;
    xdft = xdft(1:length(x)/2+1);
    plot(freq,abs(xdft)), xlabel('Hz');
    ylabel('Magnitude');
