1.问题描述
在Ubuntu15.04及更新系统中安装了Matlab 2016a，成功激活后启动，遇到了启动奔溃（crash）问题，截图如下：

2.Bug原因
引起这种错误的原因是Ubuntu15.04及以上版本包含更新版本的libstdc++.so.6，而Matlab使用的是较旧版本（versioin 6.0.17）。当Matlab首先加载
/usr/local/MATLAB/R2016a/sys/os/glnxa64 中的libstdc++.so.6.0.17时，操作系统收到一个Matlab引起的不兼容错误（incompatibility），从而引发启动奔溃（crash）。
3.修正方法
可以强制使Matlab加载由操作系统提供的更新版的libstdc++库，通过以下三个操作完成：
1].定位Matlab的安装目录，默认是/usr/local/MATLAB/R2016a ;
2].进入sys/os/glnxa6 目录
$ cd /usr/local/programFiles/MATLAB/R2016a/sys/os/glnxa64 ；
3].重命名libstdc++.so.6 共享库为 libstdc++.so.6.bak
# mv libstdc++.so.6 libstdc++.so.6.bak
MathWorks官方只对libstdc++.so.6(version 20)做了有限的测试。目前，这个Bug已经在R2016b(9.1)中修复。
