Why I get error using the following code?
syms t w;
syms g h;
g=fourier(exp(-1*(t^2)));
h=abs(g);
w=-10.1:10.1;
plot(w,h);

plot(w, subs(h))

Worked fine when I tried on the code you posted.
If you have other code for calculating spectra then you should probably post that so we do not have to guess about what might not be working.

Yes thanks! I'm sorry it works fine. (I was using fplot instead of plot).

Plot symbolic functions by using fplot.
fplot(h)

Thanks but it doesn't plot spectrum of f(t) correctly. I want to plot the spectrum of arbitrary function for example exp(-t^2) , dirac(t), ...
could you help me?
