MATLAB: What about the character #

reserved characters

Hi,
I wonder if anyone have an idea about the character #. It appears to have no use in matlab and it can neither be used in variable names,
#a = 0; %ERROR!

b.#c = 0; %ERROR!
So, does it have some use that I have still to identify, is it excluded for a reason, … I am simply curious, what is the thing with the hash?

Best Answer

There is no special thing with the hash. In some script languages it is used as the comment character, and I've seen things like
%# my comment here
You have to use alphanumeric characters for variables, functions etc, and they must not start with a number. Like #, you cannot use $, !, ยง etc.
So in principle Mathworks could have decided to allow #, but probably because it is not allowed in variable or function names in all programming languages that I know, they decided the same for Matlab.
