I would like to use Matlab to check my answers.(adsbygoogle = window.adsbygoogle || []).push({});

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:Code (Text):

clc;

syms t;

fourier(cos(t))

I would really like to be able to do something like:Code (Text):pi*(dirac(w-1)+dirac(w+1))

and get:Code (Text):

clc;

syms t;

fourier(cos(a*t))

so I can actually check harder transforms.Code (Text):pi*(dirac(w-a)+dirac(w+a))

How would I do this?

Thanks in advance :)
