a colleague of mine decided to use wrapToPi in our multi-version matlab environment and i got confused on availability. Mathworks website lists the function as member of the mappingTB in 2017a. My local matlab installation 2016b (without mappingTB) has the function, our mcc installation on R2016a complains about a missing function of that name.

Based on our documentation, the wrapToPi function belongs to the Mapping Toolbox in each release you mention above.
You can find our documentation for each release at the link below:
https://www.mathworks.com/help/doc-archives.html
You can use the command below to get the path of this function. This will tell you if you defined your own wrapToPi or you are accessing the Mapping Toolbox version.
which -all wrapToPi
