RE: Continue ignoring Error

[William Krekeler]

You want the lasterror command, combine this code snippet with the prior code 
snippet response.

try
        some_code()
catch 
  errorArray(k).error = lasterror;
end

You should be able to do that using a try-catch block. Your code would,
thus, look something like this

        failures = [];
        for k = 1:400
          try
            read_data ();
          catch
            failures (end+1) = k;
          end_try_catch
        endfor

where you should replace 'read_data' with whatever code you actually
want to run.
