Is there a method to display the error containing line in .m file, when the execution stops?

Your question sounds like:
How to pinpoint the line that errors in a "highlight some lines + F9"?

Perhaps you are looking for:
dbstop if error
or if you want to catch error inside TRY-CATCH also:
dbstop if all error
[EDITED]: In modern Matlab versions this is documented:
dbstop if caught error
Then the failing line is highlighted in the editor automatically.

It is usually indicated in the error message.
Also, help dbstack.

Under which circumstances does it (MATLAB?) show "error at" without a line number? Usually a line number is following.

The line number in the function or library used by Matlab, but not the one in the .m file.

After you get the error, execute this
l=lasterror;
fprintf('The last error was on line %d of the file called %s \n',...
l.stack.line,l.stack.name)
