That usually means that the underscore you are using is not part of the ASCII character set MATLAB recognises.
The correct underscore is:
undscr = char(95);
and the minus sign or hyphen is:
hyphn = char(45);

Thanks for the answer. If i write in the command window
undscr = char(95)
matlab answers
undscr =
'_'
so i think that the underscore is associated to the rigth ASCII value. The minus sign is correct, too.
The problem suddenly appeared while i was coding. In the previous line there was no problem, in the next one the underscore started to be in red. I don't know what happened.

Without seeing your code, I don’t either.
However, it is likely that you either left off a closing parenthesis or square bracket or curly bracket, or some other error that caused the mlint or related functions to detect an error in the previous line. Be certain everything is correct iun the previous line, and the problem will likely not recur.
