fprintf output in a parallel computing job
显示 更早的评论
Hi,
If I use disp or fprintf in a function called as a task in a parallel computing job, where does the output end up? It does not appear in the desktop window. Is it written to a file somewhere, or is it discarded completely?
Thanks in advance, Paul

If you use the batch function to submit a job, you can use the "diary" method on the job to see the output. For example
j = batch( 'disp hello' ); % submit a simple command
wait(j), diary(j) % display the output
If you use the jobs and tasks API directly, you need to set the "CaptureCommandWindowOutput"/"CaptureDiary" flag to true before submission, and check the "CommandWindowOutput"/"Diary" property after execution. (The first option is for R2011b and before, the second for the new API in R2012a).
