function y = data_num(a,b,c)
How can I find the parent function of ''data_num''?
if i am using deprpt('data_num'). It is not displaying the parent function name. It is thrwoing a error as
''Parent functions cannot be displayed in dependency reports for a single file''.
Thanks a lot

There is typically not just one caller of any given .m file, and the callers of any given .m file might not even be in any directory that is on your current MATLAB path.

function a = eliminate_m(g,h)
i know the parent function of 'eliminate_m'. When i use deprpt
('eliminate_m') still i am getting the same error and it is not displaying the parent function.

The deprpt() function is undocumented, and has been replaced in newer versions.
You can only be told the parent of functions invoked by the files you named. If you only name one file then it cannot tell what the parent is. Individual .m files do not know who calls them, but you can ask to analyze a bunch of files at the same time and see which (if any) of those files call the one you are interested in.
