How can we know whether the current execution of command is conducting inside a function or not?
When I develop a function, I frequently check some parts of the code for the function in base command envirenment.
I wonder is there any method to identify whether the current execution is conducting inside of a function or
it is conducting in the base environment.
Thanks in advance !!!

The functions nargin and nargout will error if executed at the base. So you can use try/catch
inbase = false; try; nargin; catch ME; inbase = true; end

You can call fprintf immediately upon entering and just befor leaving the function:
fprintf('Entering MyFunction().\n');
fprintf('Leaving MyFunction().\n');
If you stop at a break point, you can check the call stack on the tool bar. Or you can get the call stack from my attached function and print it out inside the function.

@Saang Bum Kim, okay. I don't see Stephen on this thread, but it looks like you've accepted the Answer from Walter so I guess everything is figured out and working now. Best wishes.
