Chinese postman problem algorithm with example matrix?

Can you provide one example for Chinese Postman Problem algorithm? One simple example with 4-5 nodes.

This is your function from site: https://www.mathworks.com/matlabcentral/fileexchange/56542-chinese-postman-problem/content/CPP.m

I need that same code with example (some matrix input) for understanding how algorithm works. Thanks.

Surely the author of the code would be the most obvious person to ask?

Who is author of the code?

[Walter Roberson]
