Problem running matlab script to background

Asked by Aristotelis on 12 Mar 2013
Latest activity Commented on by Alessandro on 11 Oct 2013
Hello, I made a script to create some map plots using functions like contourfm and quiverm. I run this script on a server and putting it to background like this:
matlab -nosplash -nodisplay -nodesktop < (name.of.script.m) > output.log &
Then I can successfuly logout the machine and the job continues until an error occurs stating: "Segmentation fault (core dumped)" leading to no results.
If I try without -nodisplay switch, no Segmentation fault appears, results are generated but I cann't logout without killing the job at the same time...
Any ideas would be helpful! Thank you in advance!

What type of image are you trying to save?
Saving to jpg, png, tiff or eps/ps is usually safer than other file formats when no desktop is present.
You could try using a different rendering method. I would recommend painters or zbuffer.
As for the second part of the question. What happens when you add "exit" as the last command in the script?

Thank you for your answer! Using -painters option solves the problem as zbuffer doesn't run in terminal mode. I already have included exit as last command. Unfortunately didn't make any difference as the code stopped before reaching the end.

Are you using OS-X or Linux? If so,

nohup matlab -nosplash -nodisplay -nodesktop -r 'try; ScriptName; catch; end; quit' > output.log &

where ScriptName does not have the .m
