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 loopwebread Products No products are associated with this question.

Now it happens that the files sometimes gives very odd data, and it is unpredictible some times. In those https://www.mathworks.com/matlabcentral/newsreader/view_thread/307275 cases I just want the loop to continue, ignoring the mathematical errors that come out from that specific file. I have say 600.000 files to go through so 5% errors doesn't matter. But it is really enoying if the loop stops at 12000 out of 600k, because of some random error. Is the there a "if any type of error -continue"? Here is an example, but it does not work. It should skip j=5, what ever error occurs there. try cc=1;nun=zeros(1,10); for j=1:10 if j==5 dum=eig(NaN); %just an example that would stop the loop. Replace with other. nun(cc)=eig(1);cc=cc+1; else nun(cc)=j*2;cc=cc+1; end end catch exception throw(exception); end nun Many thanks, Per Subject: ignore any kind of errors in a loop?

I'm calling this function inside a loop to convert a number of files. There are some cases where my .dat file is corrupted and the function cannot convert and an error occurs, stopping the loop. Now my question is: Is there any command wherein when the error occurs it should skip the current (i) value in the loop matlab try catch and go for the next increment value (in my case the next file)? matlab loops share|improve this question edited Sep 13 '10 at 15:16 gnovice 88.3k9195283 asked Sep 13 '10 at 15:07 user446468 66113 add a comment| 1 Answer 1 active oldest votes up vote 20 down vote You can do this using a TRY/CATCH statement along with CONTINUE. Place the following inside your loop: try %# Attempt to perform some computation %# The operation you are trying to perform goes here catch exception %# Catch the exception continue %# Pass control to the next loop iteration end EDIT: Amro suggests a good idea in his comment below. You may want to issue a warning showing that the error occurred and for which file, or perhaps you may even want to save a list of the files that failed to convert properly. To do the latter, you can first initialize an empty cell array before you start your loop: failedFiles = {}; %# To store a list of the files that failed to convert Then, after you catch the exception but before you issue the continue command, add the name/path of the current file being converted to the list: ... catch exception failedFiles = [failedFiles; {'currentFile.dat'}]; continue end When your loop is done, yo
