webread exiting because of bad internet connection - how to continue the program automatically

I am using webread to read data from an API. I have around 5000 links that I need to process. And my internet connection drops very often.

When the connection drops, my program exits saying, The IP address of "api.xyz.com" could not be determined.

then I have to run the code again. But how can I do this automatically. I want the code to just retry on its own instead of exiting completely.

please help!

See the section on Exception Handling in the documentation...specifically,

doc try
doc catch

Ok. I used this and it worked.

I created a while loop to read the links one by one and,

      try
          b = webread(a,options);
      catch
          continue;
      end

With this I was able to make the code try and retry automatic without exiting the program.

Thanks.
