I have a set of data points, {1, 8, 5, 0, 2}, and I want to take the DFT.
In[1]:= Fourier[{1, 8, 5, 0, 2}]
Out[1]= {7.15542 + 0. I,
0.0201626 + 3.86628 I, -2.47984 - 0.549434 I, -2.47984 + 0.549434 I,
0.0201626 - 3.86628 I}
If I shift everything by one spot, I get {8, 5, 0, 2, 1}.
In[2]:= Fourier[{8, 5, 0, 2, 1}]
Out[2]= {7.15542 + 0. I, 3.68328 + 1.17557 I, 1.68328 + 1.90211 I,
1.68328 - 1.90211 I, 3.68328 - 1.17557 I}
Is there a way that I could tell Mathematica to shift everything, or do I have to it manually?
Thank you in advance.
