MATLAB: Problems of loading http urls in matlab.

downloadinterneturlreadwebwget

I can access websites using the matlab web browser.

I can NOT download a url link using 'urlread'.

Is there any other matlab function to download the text of a url link?

Another alternative way is to use wget in matlab. I know how to save the url to a local text file and then read it into matlab, but it's inefficient since I have plenty of urls to read. Is there any way I can assign the wget-downloaded text to a variable in matlab straightforwardly?

Best Answer

Is an error being thrown when you used urlread, or is it just that the output is an empty string? What is the line of code that you are using to access the web content?

I don't have wget but (on my Mac) I use curl and can save the output from the call to a variable as per the system examples

 % build the command string
 cmd = ['curl ' 'http://www.mathworks.com/matlabcentral/answers'];
 % execute the command
 [status,cmdout] = system(cmd);
 % what is the output?
 cmdout

Try the above and see what happens!

MATLAB: How to launch a web browser or an .html file through MATLAB

You can launch a web browser or an .html file through MATLAB either by using the WEB command or the DOS command. Here are two ways to launch a web browser using MATLAB:

1. The WEB Command

This launches the URL or html file in the default browser for MATLAB - not Internet Explorer or Netscape, but the browser shipped with MATLAB. The WEB command launches the URL in this browser window. For more information, refer to the MATLAB documentation, using either

help web

doc web

at the MATLAB command prompt.

2. Using DOS commands through MATLAB.

The following example launches a new window every time a URL or an html file is called:

          dos('explorer http://www.yahoo.com');  
          dos('explorer test.html');

The following example uses the same explorer window to launch a URL or an html file:

           dos('start D:\Applications\Matlab_R12.1\help\search1.html');   
           dos('start http://www.yahoo.com');

The following example shows how to dynamically generate a URL from MATLAB variables and launch it in the browser:

googleSubSite = {'shopping','wallet','finance'};
% launch 3 browser windows or tabs
for i = 1:3
dos(['start www.google.com/' googleSubSite{i}])
end

If you are planning to launch a web browser through stand-alone code generated using MATLAB, use the DOS command and not the WEB command. (The WEB command uses objects, which are not supported when compiling with the MATLAB compiler.)
