How do I get the name of the caller function?
in [Matlab]

From: Rob Campbell on 29 Apr 2010 10:34 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

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. http://www.mathworks.com/access/helpdesk/help/techdoc/ref/throwascallermexception.html -- Steve Lord slord(a)mathworks.com comp.soft-sys.matlab (CSSM) FAQ: http://matlabwiki.mathworks.com/MATLAB_FAQ

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. |
