Getting an error thrown everytime I try to open more than one file in a matrix at a time

% rev: 0.1b
clear; 
[filename, path] = uigetfile('*.csv','Comma Seperated Values (.csv)',...
  'MultiSelect', 'on');
if filename == 0
  return
end

above is the code I am using to open multiple files at once in to a matrix to open later in the script, the problem is every time I open more than one file at a time i get an error:

    ??? Undefined function or method 'eq' for input arguments of type 'cell'.
  Error in ==> csvautomation at 8
if [filename] == 0

what should I do to avoid this error? Or get around it somehow?

This is because when you select multiple files, filename becomes a cell array of file names.

The operator == will error on a cell aray.

(~iscell(filename) && filename == 0)

This should take care of both cases! (Note: earlier suggested isempty which will not work)

That should be == instead of = there.

this works! thanks!

updated solution, Thanks Walter for catching the typo
