How to plot BER vs. Eb/No example figure?

Hello everyone,

I am a new to MATLAB, and i have a question regarding this example.

mathworks.com/help/comm/examples/parallel-concatenated-convolutional-coding-turbo-codes.html

How it is possible to plot a BER performance figure from that example, is that possible through workspace or directly from Simulink? I assume it is from workspace, if it is like that what is the proper code to plot the same figure?

Thank you very much.

Cheers.
