评论： Steffen 2014-5-9

Hello! I recently changed my Java VM to Java 1.7.0 in Matlab 2011b. I also set the environmental variable JAVA_HOME to the current JDK folder. As a result I get a lot of JAVA errors and Maltab crashes when I want to save an m.file. Hence, I want to reset Matlab to the default settings. How can I restore the default JVM? Should I delete the environmental variable? Is it also necessary to delete the JAVA_HOME system variable?

Thanks, Steffen

R2011b needs - and on Windows is bundled with - Java 6.

Either:

delete the MATLAB_JAVA (not JAVA_HOME) environment variable to use the bundled JRE.
install the latest Java 6 and set MATLAB_JAVA to point that

You can use Java 7 - but not without problems.

Do that with Windows using the System Properties option in the Windows Control Panel. On Windows 7: Start -> Control Panel -> System & Security -> System. Select 'Advanced system settings' on the left, then the Environment Variables button.
