A missing function "CommLTETurboDecoder.m"

i am reading a book "Understanding LTE with MATLAB: From Mathematical Modeling to Simulation and Prototyping". In chapter five when i run the matlab code by the name of commlteSISO.m, an error appear "Undefined function or variable 'commLTETurboDecoder'", i think this function is not present. can somebody help me overcome this error?

No, only Mathworks is authorized to distribute their code. You need to get access to an older version or you need to rewrite in terms of newer functions.

commLTETurboDecoder was present only up to R2015b.

$ ls  -l /Applications/MATLAB_R2015b.app/toolbox/comm/commdemos/commLTETurboDecoder.m

You might be able to rewrite in terms of http://www.mathworks.com/help/lte/ref/lteturbodecode.html

kindly email me commLTETurboDecoder.m file

I cannot do that. Only Mathworks is authorized to distribute their code. If you have a non-student license that is not a trial license, then you can download older versions of MATLAB than the one your license is for. I have not figured out whether students can download previous versions. Trials cannot download previous versions except by asking Mathworks for them.

Alright. Thank you for your help. i found that function m.file. can you tell me what is best version of MATLAB to run successfully all the MATLAB m.files of the book "Understanding LTE with MATLAB: From Mathematical Modeling to Simulation and Prototyping" ?

[Walter Roberson]

Sorry; I know that the book exists, but I do not have a copy and have not tried to execute the examples.

[Faizan Saeed]

Alright.
