我想以管理员模式运行MATLAB，
我有一个ubuntu 14.04和版本studiant。
如果我这样做：sudo ./matlab或sudo matlab他打印：
License checkout failed.
License Manager Error -9
This error may occur when:
-The hostid of this computer does not match the hostid in the license file.
-A Designated Computer installation is in use by another user.
If no other user is currently running MATLAB, you may need to activate.
