How do I do FFT for small amount of points?

I have a small amount of data points X=[8 7 2 4 5 1] that I want to perform FFT for in order to find the trig functions that compose this repeating pattern. Is there an easy way to code this? I've seen a bunch of code that works for continuous samples of waves but I want to downsize it.

   fft(X)

is happy to work with small number of points

Ok I got the code to work but I'm not sure how to extract the frequency of the wave and amplitudes. Here is my code so far:

Fs = 1000;            % Sampling frequency
T = 1/Fs;             % Sampling period
L = 1000;             % Length of signal
t = (0:L-1)*T;        % Time vector

X = [2 2 1 0 0 1];
for i = 1:10
    X = horzcat(X, X);
end

%plot(X);

Y = fft(X);
%plot(Y);

mag_Y = abs(Y)

plot(mag_Y);

See the first example in the fft documentation as that shows how to label the x axis with frequency
