How to open a password protected word document using Matlab?

Hi,

Would you please help me in writing a code in matlab to open a password protected word document?

below is the code I tried, but it does not work. please help me. Thank you.

    [filename, pathname] = uigetfile('*.docx','Select a file','C:\');
    filename = [filename,'.docx']; 
  password = 'secret';  
 passopen(filename,password);

   function passopen(filename, password)

 %Example filename = 'file.doc' and password = 'password'

 Word = actxserver('Word.Application');
 set(Word,'Visible',1);
 [fpath,fname,fext] = fileparts(filename);

 if isempty(fpath) out_path = pwd;
 elseif fpath(1)=='.' out_path = [pwd filesep fpath];
 else out_path = fpath;
 end
 try
 Document=Word.Documents.Open([out_path filesep fname fext],0,0,0, password);
 catch
 error('Cannot open file and/or file does not exist!');
 end

The output is : error??? Cannot open file and/or file does not exist! error in --> passopen(filename,password);
