Does Matlab have a canned set of data for FFT analysis?

What I am trying to find is a Matlab program that takes a 
known set of data for a signal, computes the FFT and 
extracts the spectral content and RMS equivalents of the 
discrete sinusoids used to assimilate the signal...

For example, if we set up a known signal comprised of

f(t) = 5 + 2sin(2*pi*100*t) + 3sin(2*pi*1000*t)

what do we get from the Matlab FFT analysis?

thanks for any advice
