% The strfind function searches for the word "Simulink".
hits = strfind(recentFile,'Simulink');
% The if statement checks for any hits.
if ~isempty(hits)
% If there are hits, the Web page will be saved locally
% using the urlwrite function.
urlwrite('http://www.mathworks.com/matlabcentral/fileexchange/
loadFileList.do?objectType=fileexchange&orderBy=date&srt3=0',
'contains_simulink.html');
end;
MATLAB saves the Web page as contains_simulink.html.
Creating and Decompressing Zip Archives
Using the zip and unzip functions, you can compress and decompress files
and directories. The zip function compresses files or directories into a zip
archive. The unzip function decompresses zip archives.
Example — Using the zip Function
Again building on the example from previous sections, the following code
creates a zip archive of the retrieved Web page:
% The urlread function loads the contents of the Web page into
the % MATLAB workspace.
recentFile =
urlread('http://www.mathworks.com/matlabcentral/fileexchange/
loadFileList.do?objectType=fileexchange&orderBy=date&srt3=0');
% The strfind function searches for the word "Simulink".
hits = strfind(recentFile,'Simulink');
% The if statement checks for any hits.
if ~isempty(hits)
