MATLAB: Plotting dirac delta function’s spectrum

plot

I used the following code to plot the spectrum of some functions. but it doesn't work for the function dirac(t-t0) at t0=0. How can I fix it?
   syms t w;
  syms g h U;
  g(w)=fourier(dirac(t));
  h=abs(g);
  w=-10:.5:10.1;
  U=angle(g);
  figure;
  plot(w, subs(h));
  figure;
  plot(w,subs(U));

Best Answer

The Fourier (and Laplace) transforms of the Dirac delta function are uniformly 1 for all omega (or ‘s’).
That is the result you get in ‘g(w)’.
