Matlab Compiler: Difference between the -a and -I option?

Can anyone explain what is the difference between the -a and -I option of the mcc compiler command?

A small description is given here: https://se.mathworks.com/help/compiler/mcc-command-arguments-listed-alphabetically.html

• -a path: Add path to the deployable archive.
• -I directory: Add folder to search path for MATLAB files.

but I'm not sure what is the difference between the two.

Hm, that explanation is indeed too short be certain. Here's how I read the definitions:

the -a option will absolutely add files to your deployed file, including non-matlab files
the -I option will specify which folder to search for matlab files that your main .m file uses, but it
       does not guarantee all files in this folder will be added. mcc uses a dependency checker
       to determine which files to include into your deployed files.
