How can I display the exit status of a compiled MATLAB application run from a shell script on Linux?

When running a MATLAB application compiled with MATLAB Compiler from a shell script on Linux, does the exit status set by the "exit(N)" function automatically appear in the standard output or standard error? If not, how can I display or log the exit status after execution?

Example Shell Script:

#!/bin/bash

./compiled_matlab_app

By default, the exit status set by the "exit(N)" function in a compiled MATLAB application is not printed to standard output or standard error. However, after your application finishes running, the exit status is stored in the shell variable "$?". To display this exit status, you can add a line to your shell script to echo the value of "$?" after executing your compiled application. The updated shell script with the added line is shown below.

#!/bin/bash

./compiled_matlab_app
echo "Exit status: $?"

This will print the exit status to the terminal, allowing you to view or log the value returned by your MATLAB application.
