I would like to use Matlab to check my answers.
For example, I want to find the Fourier transform of [tex] \cos \omega_0 t [/tex].
I know the answer is:
[tex] \pi ( \delta(\omega - \omega_0) + \delta(\omega + \omega_0)) [/tex].
How do I do this in Matlab. All I can find is something like this:
This returns:
I would really like to be able to do something like:
and get:
so I can actually check harder transforms.
How would I do this?
Thanks in advance :)

Code:
clc;
syms t;
fourier(cos(t))
This returns:
Code:
pi*(dirac(w-1)+dirac(w+1))
I would really like to be able to do something like:
Code:
clc;
syms t;
fourier(cos(a*t))
and get:
Code:
pi*(dirac(w-a)+dirac(w+a))
so I can actually check harder transforms.
