The p-files are files for which the code has been obscured, most probably deliberately so that people cannot see the code:

Although it may be possible, it will not be easy to see what code it has. You can ask the creator of the file for the m-file, but most probably you will not get it as they created the p-file and not released an m-file.

Constantino Carlos Reyes-Aldasoro is correct. If you want to see the implementation of a P-coded file you will need to ask the author or distributor of that file for the corresponding plain text file.

If this is a P-coded file distributed by MathWorks generally we will not provide the corresponding plain text script, function, or class file. My guess from the name is that it simply sets some parameters (based on the inputs with which that function is called?) on a controller object. I suspect if you assume that's what it does you should be able to understand what the rest of the code around it is doing.
