Removal of Handle Graphics support under -nojvm startup option
When you start MATLAB with the -nojvm startup option, Handle Graphics
®
functionality is not supported. (The -nojvm option is available for UNIX
®
platforms; see
background information on the matlab (UNIX) reference page.)
Some aspects of MATLAB and related products use Handle Graphics in a way that
might not be obvious. This includes anything that is based on or works using figures in
MATLAB. Here is a summary of the affected features:
• Creating figures and performing plotting tasks, such as using the plot, axes,
getframe, and gcf functions.
• Printing figures and using related functions such as print, hgexport, and saveas.
• Creating GUIs in MATLAB using GUI-building functions such as warndlg.
• Using Simulink scopes and printing Simulink models.
If you use the -nojvm startup option and use Handle Graphics functionality, MATLAB
produces an error.
Compatibility Considerations
To avoid the error, start MATLAB without the -nojvm startup option:
• If you have been using the -nojvm startup option to work in a command line
environment or because you do not use the MATLAB desktop, use the -nodesktop
startup option instead.
• If you have been using the -nojvm startup option because of memory or performance
benefits, look for other ways to gain those improvements when you start MATLAB
without the -nojvm option. See topics in Performance and Memory.
• If you want to continue to use the -nojvm startup option, remove the code that is now
producing the warnings.
-noFigureWindows startup option suppresses figures on Linux and
Mac platforms
When you start MATLAB with the -noFigureWindows startup option, MATLAB
disables the display of figure windows.
