R14SP3
23-8
previous releases ran the demos as a function. This means that now the demo's variables
are created in the base workspace. If you have variables in the base workspace when
you run an M-file demo, and the demo uses an identical variable name, there could
problems with variable name conflicts. For example, your variable could be overwritten.
The demo's variables remain in the base workspace after the demo finishes running until
you clear them or quit MATLAB. Another change is that figures are not automatically
closed when you end the demo.
echodemo Function Added to Replace playshow function
There is a new echodemo function that replaces playshow. The Demos browser uses
echodemo to execute M-file demos when you click the Run in the Command Window
link.
Compatibility Considerations
The playshow function is deprecated in favor of the echodemo function. In a future
release, the playshow function will be removed. In practice, both echodemo and
playshow are helper functions for running demos. It is unlikely you would ever call
either playshow or echodemo directly, and especially not in M-files.
Add Demos to Favorites
You now can add published M-file demos to favorites.
Adding Your Own Demos Type Tag Now Supported
If you add demos for your own toolbox, you can use the new <type> tag for a
<demoitem> to identify the type of demo in your toolbox's demos.xml file.
Bug Reporting System Introduced
You now can view bugs fixed with this release, as well as any known bugs using the Bug
Reports database in the Support section of the MathWorks Web site. The MathWorks
continuously updates the database to add any newly found bugs and compatibility issues,
as well as any new workarounds and solutions. The system includes bugs found and fixed
in R14SP2 and later releases.
