I'm running Matlab R2008b. I would like to be able to determine whether a current workspace is the 'base' workspace. ('base' in the same context as the assignin and evalain statements.)

For example, I'd like to run something like

>> which_space_am_i_in()

and have it return 'base', or true, or something indicating the command-line workspace versus some workspace inside a function.

The basic functionality I'm looking for is I want a function to act differently depending if it's called from the command line (could be a script run from the command line) or from some other function.

Are there any builtin functions or simple ways to do this?

Check out dbstack.

Well, it's less elegant than I would've hoped, but I guess (length(dbstack)==1) provides a reasonable logical test. Thanks for the info.

Okay, I'll bite -- what's your use case? What should your function do
differently if called from the command line than if it's called from a
function?

Here's what I use, but beware trying to using it in debug mode. The dbstack command is insensitive to dbup/dbdown etc...


function where
%The current location in the function stack



[s,wsi]=dbstack('-completenames') ;


str='In base workspace';


if length(s)>1,

str=s(2).file;

end


disp(' ');
disp([' ' str]);
disp(' ');
