We can catch error line by
dbstop if all error
dbstop if error
dbstop if caught error e.t.c
I have no idea how to catch the above mention error(Index exceeds matrix dimensions) line in matlab 2016a?

Shakir - why can't you use dbstop if error? Are you saying that this doesn't work in r2016a?

Yes, it does not work for me and the error is not giving any information more than above mentioned one

''Index exceeds matrix dimensions'' error line
This is not the complete error message, but there must be a file name and line number. Then:
dbstop in FILENAME at LINENO
stops there. But this stops also, if no error occurred.
What about:
dbstop if error IDENTIFIER
or in your case:
dbstop('if', 'error', 'MATLAB:badsubscript')
Nevertheless, Geoff's idea should be working already: dbstop if error does catch your error also. So why does this not work?

I also astonished that why the above mentioned codes are not working

@Shakir Hussain: It would be useful, if you explain the problem you have. "Not working" is not specific enough to allow for a matching solution. Post the corresponding code and explain, what you observe exactly. You can enclose the code in try, ..., catch ME, end and display the contents of ME.
