MATLAB Finding DFT and DTFT of 12-Point Sequence with MatLab

[louie]

I'm considering the 12 –point sequence x[n] which is defined as x[n] = {1, 2, 3, 4, 5, 6, 6, 5, 4, 3, 2, 1}.

I'd like to use Matlab to find the DFT (X[k] of x[n]) and DTFT (X(e^jw) of x[n]).

I realize that the DFT is sampled version of DTFT, and I want to show this graphically using Matlab, but I'm not too familar with Matlab's syntax.

Thanks in advance,

Louie
