Is there any method to set breakpoints to all the lines of a .m file, except manually one by one?

As Sean and Jiang I do not think that this is useful. But if you are sure that you need it:
i = 1;
while 1
try
dbstop(FuncName, sprintf('%d', i));
i = i + 1;
catch
break;
end
end

Why not just set one on the first line and step through it?
doc dbstop
doc dbstep

How does it work any differently than having a break point on that line?

Why do you need that? You can debug by running code line by line (pressing F10).

That doesn't make any sense. Typing F5 or F10 WILL work, even if you're stepping on a line that generates an error. How would an error get generated anyway, if not due to executing a statement in the loop that you are in? Doesn't make sense, unless you had some kind of parallel processing going and THAT process generated the error. Even that doesn't negate the fact that F5 and F10 will still work.

Yes, you can construct a script that would do this by issuing "dbstop" calls on your behalf. But like the others I do not see much point in it.

@Horia: Did my code what you want? If sets a break point in each line of the M-file, whose name is store in the variable FuncName. Does this differ from the requested behaviour, and if so, how?

If you were plotting a variable named values then
values(values<0) = nan;
MATLAB knows to skip plotting points with value nan.
