Exit the current Octave session. If the optional integer value status is supplied, pass that value to the operating system as the Octave’s exit status. The default value is zero.
Register a function to be called when Octave exits. For example,
function last_words () disp ("Bye bye"); endfunction atexit ("last_words");
will print the message
"Bye bye" when Octave exits.
The additional argument flag will register or unregister
fcn from the list of functions to be called when Octave
exits. If flag is true, the function is registered, and if
flag is false, it is unregistered. For example,
after registering the function
atexit ("last_words", false);
will remove the function from the list and Octave will not call
last_words when it exits.
atexit only removes the first occurrence of a function
from the list, so if a function was placed in the list multiple
atexit, it must also be removed from the list
