Sometimes there is something wrong with the page it’s trying to read which causes the script to stop and display the error. From what I understand you can put the command within a “try” command to continue despite the error like this:try webread(‘www.something that could or could not generate an error.com’) catch continue end First of all; is that the correct way of writing it or would I need to specify anything more after writing “catch”? And can I modify this so that instead of continuing the script it restarts it from the next iteration in the loop? If I write:for i=1:100 try webread(‘www.something that could or could not generate an error.com’) catch end %I want this to cause the loop to jump up to the next value of i and restart the loop end end Matlab won’t understand what I mean with my double end statement. Is there some other way of doing this? I want my script to always ignore errors and just try again with a new iteration. 0 Comments Show all comments Tags errorfor loopwebre
