Plot the magnitude and argument of the Fourier transformed function in frequency domain.

I am not sure how to plot the magnitude and argument of the code I have so far:

>> t=0:20;

>> n=1;

>> sig=1;

>> f=exp((-(t-n).^2)/2).*sin(n.*t);

>> plot(t,f);

>> tn=length(t);

>> fft(f,tn);

>> z=fft(f,tn);

>> abs(z);

>> angle(z);

How should I plot this?
