What does '-' mean in matlab code

Can some one explain what this line here does? This is part of an old matlab code I need to reuse for my work

matdir = [params.ariens '-' num2str(dirtimes(ii))];

I'm especially confused about the '-' part. Thanks a lot in advance.

Single quotes are used to create a string literal so '-' simply creates a string containing the hyphen character. In MATLAB, [ ... ] performs horizontal concatenation so the line that you have shown concatenates the string stored in params.ariens, the character '-' and the number dirtimes(ii) converted to a string using num2str to creat one long string made up of those three strings.

For example:

c = ['abc', '-', 'def']
%   abc-def

class(c)
%   char

d = ['abc', '-', num2str(10)]
%   abc-10
