This seems like a bug in the 'categorical' class

if I define a cellstr:

>>n={'a','b','b','c'}

I can make it a categorical variable:

>> c=categorical(n)

c = 

       a      b      b      c

and it will display correctly, but if one of the strings contains a parenthesis:

>> n={'a(','b','b','c'}

n = 

      'a('    'b'    'b'    'c'

>> c=categorical(n)

c = 

      'a('    ' $1 '    ' $1 '    'c'

The display after that element is showing some kind of pointer instead of the value.

There is also a problem with close-paren, but a little different.

>> n={'a)','b','b','c'}

n = 

      'a)'    'b'    'b'    'c'

>> c=categorical(n)

c = 

       a )'     b '     b '     c '

Doesn't happen with [.

Clearly seems to be parse error in the display function for the class.

Anyway, thought you should know and wondering if there is a fix/workaround.

Thanks, Michael

Michael, thanks for reporting this. Not sure what version of MATLAB you're using, but this was fixed in R2014b:

>> categorical({'a(','b','b','c'})
ans = 
     a(      b      b      c 
>> categorical({'a)','b','b','c'})
ans = 
     a)      b      b      c

So I've heard. I have 2013b. Thanks.
