Create a function which returns values into input variables in a single call.

For example, given a function:
function str=addslash(str) % add slash to a directory name
if str(end)~='\', str(end+1)='\'; end
end
Then I call it for a couple of directories:
dir1=addslash(dir1);
dir2=addslash(dir2);
dir3=addslash(dir3);
...
How to rearrange the function, in order to call it with one statement like this (number of input arguments may vary):
addslash(dir1, dir2, dir3, ...);
or like this:
addslash('dir1', 'dir2', 'dir3', ...); % dir1, dir2, dir3... are names of variables

If you just want to compare the paths, then removing the trailing file separator character would be simpler. See my answer.

function nargin=addslash(varargin) % add slash to a directory name
N = length(varargin) ;
nargin = cell(N,1) ;
for i = 1:N
str = varargin{i} ;
if str(end)~='\'
str(end+1)='\';
end
nargin{i} = str ;
end

@KSSV, that nargin should be varargout.
@bbb_bbb, The problem is, how to write the results back to the input variables?
If you need to do that, you've gone wrong in the design of your code. Clearly, since you want to apply the same code to multiple variables that means that these variables are related in some way. Therefore, you shouldn't have multiple variables but just one variable that holds the content of all these variables, an array, cell array, whatever container you want. the problem then goes away, just loop over the content of that container.
A very simple rule: If you number variables, stop, you're doing it wrong.
Stephen had a very valid point in the last part of his comment

This will work on one single string or char vector, or on a cell array of them:
C = strcat(regexprep(C,'\\$',''),'\')
You can easily define a function handle for it:
addslash = @(C) strcat(regexprep(C,'\\$',''),'\');
Which makes calling it trivial:
>> addslash('hello')
ans = hello\
>> addslash('world\')
ans = world\
>> C = addslash({'ab','cd\','ef\gh'});
>> C{:}
ans = ab\
ans = cd\
ans = ef\gh\
EDIT: For your usecase, it would be simpler to remove the trailing slash:
strcmpi(regexprep(A,'\\$',''),regexprep(B,'\\$',''))
