hi everyone, how to solve this problem: 'wget' is not recognized as an internal or external command?

   ERROR:- 'wget' is not recognized as an internal or external command, 
   operable program or batch file. 

   output_directory = 'sbu_images';
   urls = textread('SBU_captioned_photo_dataset_urls.txt', '%s', -1);
   if ~exist(output_directory, 'dir')
     mkdir(output_directory);
   end
   rand('twister', 123);
   urls = urls(randperm(length(urls)));
   for i = 1 : length(urls)
       if ~exist(fullfile(output_directory, [regexprep(urls{i}(24: end), '/','_')]))
           cmd = ['wget -t 3 -T 5 --quiet ' urls{i} ...
      ' -O ' output_directory '/' regexprep(urls{i}(24: end), '/', '_')];
     unix(cmd);
     fprintf('%d. %s\n', i, urls{i});
       end 
   end

The error message is clear: Your unix system does not know a wget function. Note that this is not a Matlab problem. Most likely it is solved either by installing the package, which contains wget or by including the folder containing the executable to the PATH (of the OS, not of Matlab).

Thank you, I download wget zip file --> extracted--> add to the system path --> restart matlab---> done.

Hope it help. Thank you once again.

Not really, yet. Because you didn't say where you found that wget zip file. Where did you get it from?
