1. Which bug reports do you publish?
   Published bug reports are for bugs that have been reported in this system that may be of interest to customers, based on general use of our products. Bug reports are updated by the development team as more information or a new release becomes available. Updated information could include provisions for any known workarounds or file replacements. A bug report is available for each bug that either exists in or has been fixed in Release 14 SP2 or later. Information is not available for all bugs, known or unknown, including bugs in prior releases.

2. Quick Facts
   • What is the cost?
     Free, however a login is required. You can create a MathWorks Account without having a MathWorks product license. The process takes just a few minutes. See the full list of benefits of having an account.
     
     
   • Which releases are covered?
     R14SP2 and later. Bug report information is available for bugs that either exist in or were fixed in Release 14 SP2 and subsequent releases. Information is not available for all bugs.
     
     
   • What can I do?
     You can:
     
     • Search for a keyword, Bug ID, topic, or snippet of an error message
     • Apply filters to search by release (exists in, fixed in, or originated in a particular release), product (bugs in a specific product), and other criteria (bug has an attachment or a workaround)
     • View search results in summary form or expand the report to include a detailed description, workaround information (if available), releases in which the bug exists or is fixed, and an opportunity to provide feedback on whether the bug affects your work
     • Add a bug to your watch list
   
   
3. How do I determine which product release and version I am using?
   

   To determine which version and release of a product you are using, type the following at the MATLAB^® command line:

   ver

   You will see the following information, specific for your installation:

   ----------------------------------------------------
   MATLAB Version 7.6 (2008a) 
   MATLAB License Number: 000000
   Operating System: Microsoft Windows XP Version 5.1
   (Build 2600: Service Pack 2)
   Java VM Version: Java 1.6.0 with Sun Microsystems Inc.
   Java HotSpot(TM) Client VM mixed mode
   -----------------------------------------------------
   MATLAB                            Version 7.6        (R2008a)
   Simulink                          Version 7.1        (R2008a)
   Aerospace Blockset                Version 3.1        (R2008a)
   Aerospace Toolbox                 Version 2.1        (R2008a)
   Bioinformatics Toolbox            Version 3.1        (R2008a)
   Communications Blockset           Version 4.0        (R2008a)

   The first line shows the version and release for MATLAB. The example above refers to version 7.6 and Release 2008a or R2008a.

   The lines of output shown below the line indicate the installed products, their corresponding versions, and releases. This section of output may be rather lengthy, depending on the number of products you have installed. You may need to scroll up to locate your product name.



4. What do the bug statuses mean?
   

   Exists In

   Either the bug exists in the specified Release or the MathWorks is currently investigating this bug or working on a fix.

   Fixed

   The bug has been fixed in the shipped release and version specified.



5. How can I be kept apprised of new bugs or bug updates?
• For individual bugs: Individual Bugs can be added to your Watched Bugs list by clicking on the check mark in the Watch column. Your Watched Bugs list will track individual bugs that are of interest to you. You can then set your e-mail preferences for the Watch Bugs list to get e-mail notifications when updates are available.
• For a search you have run: You can save a search you have run and set up e-mail notifications, which enables you to retain the search for quick reference in future and receive e-mail notifications for updates that occur to any of the bugs in your saved search. You can also subscribe to an RSS feed to receive updates on bugs.


6. Why aren't all bugs shown? Why isn't the bug I reported showing up?
   Bugs reported in this system are those that may be of interest to customers, based on general use of our products. Bugs are updated by the development team as more information and releases become available. This includes provisions for any known workarounds or file replacements. Bug report information is available for bugs either exist in or have been fixed in Release 14 SP2 or later. Information is not available for all bugs, known or unknown, including bugs in prior releases. If you feel your bug should appear in this table, contact technical support and ask that your bug be nominated as a bug report.
   
   
7. Does this interface include information on enhancement requests?
   This interface communicates information only on bugs that The MathWorks is aware of and that are likely to be of interest to customers. You can search the knowledge base for information on enhancements.
   


8. How are the bugs sorted in the table view?
   Bugs are sorted first by the date modified. You can sort them by bug ID or by product by clicking on the column header.
   


9. How can I search for individual bugs?
   You can search by any of the fields on the detail page for an individual bug. This means you can use any combination of search terms, including product and release as well as keywords, to perform a search. You can also search on the exact bug report ID.
