You're trying to specify a function to be run at runtime and that function
was not necessarily present when the GUI was compiled? That will not work. A
compiled application can only access functions, scripts, and classes that
were compiled into the application. You can't "add in" new
functions/scripts/classes at runtime.

If you're trying to specify a function that WAS present when the GUI was
compiled but is called only via FEVAL, EVAL, etc. then you need to tell
MATLAB Compiler at compiled-time that it should include those functions in
the application. See "Does the application begin execution and result in
MATLAB or other errors?" on this documentation page.
