To convert a time domain signal into frequency domain, one must use the Fourier transform to do so. MATLAB has a function fft which is a Fast Fourier Transform algorithm designed to implement the Fourier Transform on digital signals.
Please go through this documentation to know more:

Hope this helps

I used the fft in Matlab and it works but how does it work ? i am trying to look in the internet but all they say about fft is that it converts time domain signal into frequency domain... but how ? they didn't mention..
Any idea will be helpful...
Thanks in regards

It uses Fourier transform, it's a mathematical method to handle functions, you can google it
