曾經試過很多次，都沒有成功，連安裝的界面都進不去。原因是在64位的機器上裝了64位的系統，但是matlab的各種版本似乎都對64bit非常反感，只好作罷。畢竟那個時候還有Windows嘛，在Linux下裝matlab只是興趣使然。
昨天重新安裝了Ubuntu系統，徹底的沒有Windows了。今天嘗試了很久，終於裝上了。簡單記錄下過程，今後重裝還有參考
1、一定裝7.0及以上版本。6.5的能進入安裝界面，但是在驗證key文件的時候總是過不去。網上有人提出了修改系統時間的辦法，試過了，未遂；嘗試7.0，沒有問題；
2、安裝過程很順利，運行時會出現比較大的問題：simulink無法啟動，而且輸入的命令會直接導致程序崩潰，ctrl c都無法響應，只能用kill －9的辦法。網上提供了一套解決方案，copy如下：
simulink有問題，下面是各種錯誤信息的解決方法。
??? Can't load '/usr/local/matlab/bin/glnx86/libmwsimulink.so': libXft.so.1: cannot open shared object file: No such file or directory
Solution:
[root@localhost matlab]# updatedb && locate libXft.so
/usr/lib/libXft.so
/usr/lib/libXft.so.2
/usr/lib/libXft.so.2.1.2
[root@localhost matlab]# ln -s /usr/lib/libXft.so.2 /usr/lib/libXft.so.1
然後會出現
??? Can't load '/usr/local/matlab/bin/glnx86/libmwsimulink.so':
/usr/local/matlab/bin/glnx86/libqt-mt.so.3: undefined symbol: XftFreeTypeOpen
Solution :
# install qt 3.3
# mv /usr/local/matlab/bin/glnx86/libqt-mt.so.3 /usr/local/matlab/bin/glnx86/libqt-mt.so.3_back
# ln -s /usr/lib/libqt-mt.so.3.3 /usr/local/matlab/bin/glnx86/libqt-mt.so.3
然後又會出現
/usr/local/matlab/bin/glnx86/../../sys/os/glnx86/libgcc_s.so.1:
version `GCC_4.2.0' not found (required by /usr/lib/libstdc++.so.6)
或者
/usr/local/matlab/bin/glnx86/../../sys/os/glnx86/libgcc_s.so.1: version `GCC_3.3' not found (required by /usr/lib/libstdc++.so.6)
Solution :
# find libgcc_s.so.1 for 3.3 or 4.2
or a one for all way
Matlab was built with a different version of gcc (3.2.3 in the case of R14SP2), whereas Fedora Core 5 has gcc 4.1.0. The following trick is alluded to in the file ${MATLAB}/sys/os/glnx86/README.libstdc++, but you need to be the root user. Type these commands ...
# cd $MATLAB
# cd sys/os/glnx86
# mkdir old
# mv libstdc++.* libg2c.* libgcc_s* old
When matlab is restarted, it will then use the system libraries instead of those supplied by Mathworks. And then all is fine and well with the world. Note that if this sort of thing happens with an x86-64 machine, then the directory in question would be ${MATLAB}/sys/os/glnxa64 instead of ${MATLAB}/sys/os/glnx86.
