Hi Rakesh,
In GNU Radio, FM demodulator is implemented digitally as
a = present_complex_sample * conj(previous_complex_samples)
out[current] = some gain * arctan ( imag(a), real(a) ); //demodulated FM signal
So, you can also implement the same for demodulating FM signal in MATLAB. Recorded FM files may already be available in internet. So, use that file and test your MATLAB code.
For connecting USRP to Matlab, toolbox is already released by Mathworks from 2011 versions. If using older version of Matlab, you can use

Hope this might help you,
Senthil
