If my data is 2,2,2,5,5,6

Shouldn't

Amplitude =2 and frequency =3

Amplitude =5 and frequency =2

Amplitude =6 and frequency =1

%Read in the data

data = xlsread('time.xls');

%Analyze the frequency components.

y=2*abs(fft(data))/length(data);

%Plot frequency versus frequency componant magnitude, circle f_max

figure

plot(x,y)
