Thread Subject:

How do I get the name of the caller function?

Hi,

Say I write function "X" which I intend to be called by other Matlab functions. Is there a command I can insert into X which would report the name of the function that called X?

I don't want to have to pass the name of the caller function to X as an input variable. i.e. this would not be a suitable solution:
X(inArgA,inArgB,mfilename)

Cheers

Look at the dbstack function which gives you the entire calling sequence.

Nice one!
Thanks.

How are you planning to use this functionality? If you're trying to throw
an error message "as though" it were coming from the caller function,
generate an MException and use its throwAsCaller method.

Steven, for the record what I was doing was

function varargout=X(varargin)
if nargout>2
disp("you're using function X with the old output format")
end

Being able to report who called function X is just a nicety so that people know where to look when updating code. dbstack does what I needed.

If you want this for the main function in the file, you can use
mfilename.
