I am afraid a lot of children's shoes after upgrading the Yosemite have encountered the problem of MATLAB.
Previously reproduced an article wrote the installation method, this article said to solve the retina screen display fuzzy approach.
Because the MATLAB 2014a uses its own Java, the version is relatively low, resulting in the inability to support the retina screen.
You can view the Java version by entering Version-java in the MATLAB command window.
How to solve the retina screen display (there are many ways online, I find this is the simplest and easiest way to understand):
Step 1:
Download and install the latest Java
http://www.java.com/zh_CN/
Step 2: Install Java inside the system into Java within MATLAB for the simplest upgrade
Then the path to Java within the system is
/Library/Internet plug-ins/javaappletplugin.plugin/contents/home/
The Java path for MATLAB is
/applications/matlab_2014a.app/sys/java/jre/maci64/jre/
Then all the files in the above folder are covered in MATLAB Java!
OK, so it's done!
