Matlab Error Message

Hi

I have been running a simple video compression algorithm and after a few hours I got the below error message. Does anyone know what this is?

Exception in thread "AWT-EventQueue-0" java.lang.NullPointerException at com.mathworks.mlwidgets.array.ValuePanel.cleanup(ValuePanel.java:392) at com.mathworks.mde.array.ArrayEditor$DTCL.clientClosed(ArrayEditor.java:191) at com.mathworks.mwswing.desk.DTClient.close(DTClient.java:845) at com.mathworks.mwswing.desk.DTCloseTransaction.close(DTCloseTransaction.java:124) at com.mathworks.mwswing.desk.DTGroup$GroupCloseTransaction.close(DTGroup.java:1130) at com.mathworks.mwswing.desk.DTCloseTransaction.query(DTCloseTransaction.java:97) at com.mathworks.mwswing.desk.DTCloseTransaction.start(DTCloseTransaction.java:65) at com.mathworks.mwswing.desk.DTGroup$GroupCloseTransaction.start(DTGroup.java:1118) at com.mathworks.mwswing.desk.DTGroup.attemptCloseDocked(DTGroup.java:1139) at com.mathworks.mwswing.desk.DTGroup$CloseDocumentsAction.actionPerformed(DTGroup.java:1772) at javax.swing.AbstractButton.fireActionPerformed(Unknown Source) at javax.swing.AbstractButton$Handler.actionPerformed(Unknown Source) at javax.swing.DefaultButtonModel.fireActionPerformed(Unknown Source) at javax.swing.DefaultButtonModel.setPressed(Unknown Source) at javax.swing.plaf.basic.BasicButtonListener.mouseReleased(Unknown Source) at java.awt.AWTEventMulticaster.mouseReleased(Unknown Source) at java.awt.AWTEventMulticaster.mouseReleased(Unknown Source) at java.awt.Component.processMouseEvent(Unknown Source) at javax.swing.JComponent.processMouseEvent(Unknown Source) at com.mathworks.mwswing.MJButton.processMouseEvent(MJButton.java:312) at java.awt.Component.processEvent(Unknown Source) at java.awt.Container.processEvent(Unknown Source) at java.awt.Component.dispatchEventImpl(Unknown Source) at java.awt.Container.dispatchEventImpl(Unknown Source) at java.awt.Component.dispatchEvent(Unknown Source) at java.awt.LightweightDispatcher.retargetMouseEvent(Unknown Source) at java.awt.LightweightDispatcher.processMouseEvent(Unknown Source) at java.awt.LightweightDispatcher.dispatchEvent(Unknown Source) at java.awt.Container.dispatchEventImpl(Unknown Source) at java.awt.Window.dispatchEventImpl(Unknown Source) at java.awt.Component.dispatchEvent(Unknown Source) at java.awt.EventQueue.dispatchEvent(Unknown Source) at java.awt.EventDispatchThread.pumpOneEventForFilters(Unknown Source) at java.awt.EventDispatchThread.pumpEventsForFilter(Unknown Source) at java.awt.EventDispatchThread.pumpEventsForHierarchy(Unknown Source) at java.awt.EventDispatchThread.pumpEvents(Unknown Source) at java.awt.EventDispatchThread.pumpEvents(Unknown Source) at java.awt.EventDispatchThread.run(Unknown Source)

I would recommend reporting this to MathWorks Tech Support.

[Sean de Wolski]

I've just learned to ignore those.

[Oleg Komarov]

I second Sean.

[Joseph Areeda]

While I'm very good at ignoring these, my users aren't.

Any idea how to hide these things?

[Matt Fig]

Haha, glad I am not the only one who ignores the red screen of death.

I have been getting these types of errors also and don't know why. I have a main outer loop that, essentially does the same sort of processing just on a slightly different dataset each time in the main loop. It will go without error for 6 - 15 iterations at a time and then suddenly spit out the same type of errors you show above. It hasn't killed/stopped the main loop from completing, but it's a bit troubling and I usually re-run the loops where the error occurred and/or double-check to make sure the processing looks like it worked properly on those. I'm using matlabpool 8 and fitting lots of functions to lots of data in the loop.
