Why do I receive warnings saying that a file or function is "excluded from packaging" in the Packaging Log or MATLAB Command Window, while trying to create a standalone application using MATLAB Compiler?

Warning: In "C:/path/to/mfile.m", "function" are excluded from
packaging for the MATLAB Runtime environment according to the MATLAB Compiler license.
Either remove the file or function from your code, or use the MATLAB function
"isdeployed" to ensure the function is not invoked in the deployed component. 

In older versions of MATLAB:

[Warning: Excluded "C:/path/to/mfile.m",
reason: The file or function has been excluded from packaging for the "MCR"
target environment according to the "Compiler" license.  Either remove the file
or function from your code, or use the MATLAB function "isdeployed" to ensure
the function is not invoked in the deployed component.]

MATLAB Compiler does not support the deployment of all built-in functions. If a user invokes an unsupported function in a deployed application, the application will not work as expected. Starting MATLAB R2017a, we added a feature to warn users if they are using an unsupported function in their deployed application.

Ensure that you are not using any unsupported functions or Toolbox functionality in your deployed application. Refer to the following resources for a complete list of unsupported functions:
