Hello World,
I am using the parfor command to run a job on multiple processors. I am running the same function on over 100 files and the function works for most files but not all. I am getting an error which indicates at what line the error occurred in my function and sub-functions but does not indicate on what file the error occurred.
Is there a way I can have matlab output the more information about where the error occurred?
Example:
-------------------------
% Run_all_files_script.m
parfor fileNumber = 1:10
main_function(FileName(fileNumber));
end
-------------------------
example of error:
"Error in Run_all_files_script (line ##)
parfor fileNumber = 1:10"
Is there a way I can output what "fileNumber" is equal to at the time of error?
Thanks,
-Tom-

parfor ii = 1:100
try
process_file(ii)
catch
error(['Error in File ' num2str(ii)])
end
end
Try/catch is probably the easiest.
