Is it possible to use Matlab to retrieve the data from Simulink from this block diagram and plot the transfer function?

Yes. It is called linearization. If you have access to the Control System Toolbox and/or Simulink Control Design, you can use linearization to extract a transfer function between two operating points. Take a look at:
Your question is a bit ambiguous, since you need an input and an output to construct and plot a transfer function. Just reading "out.in" will not be sufficient to plot a transfer function.
