Failed to call gfprimfd() in MATLAB R2012b

Question

I wish to use this function whose documentation can be found here. However, there seems to be no such function in my MATLAB.

>> help gfprimfd

gfprimfd not found.

Use the Help browser search field to search the documentation, or
type "help help" for help command options, such as help for methods.

Then, I noticed that the documentation actually writes "R2014a".

Does that mean the function is not included in my R2012b version? Besides installing a R2014a version, what can I do to use this function?

You probably don't have the Communications System Toolbox. See the output of ver.
