自用MATLAB2012a安装教程

ps:自用，里面用到的图片大部分是别人分享的，所以会有英文中文不统一的情况，参考的教程原文链接也贴在文章里了。

—————————————————————————

进入linux系统，在桌面单击右键打开终端，先root，即输入 ：

sudo su

接着输入密码，完成root

1.安装
我从师兄那里拷过来的MATLAB就是一个ISO包，所以跟着别人的教程捣鼓了半天才意识到：我跟他们的教程里一开始的步骤应该是不一样，我这个能直接在linux系统上挂载（双击）

打开终端，输入：

cd /media/k/MATHWORKS_R2012A

其实cd之后的就是你挂载的ISO的路径，这是我的路径，可以根据自己的情况替换 cd 后的路径进入该目录
继续输入：

ls

ls是列出当前目录下的所有文件，这里会看到 install
接下来继续输入：

cd .. 

意为返回上一层
输入：

sudo /media/k/MATHWORKS_R2012A/install 

这时候就开始执行安装文件了

这一部分参考：https://blog.csdn.net/minione_2016/article/details/53313271

默认的安装路径是 /usr/local/，因为我对linux系统不熟，没注意到这个问题，更别说更改安装路径。

在安装过程中一定要记得自己的安装的路径（比如我的就是 /usr/local/MATLAB/R2012a，如果是首次安装，系统会提示没有该文件夹询问你是否要建立一个新的，选择YES就可以了）

选择Use a File Installation Key - Next

出现一个需要输入序列号的框，序列号在 /MATHWORKS_R2012A/crack/install.txt 里查看（如下）

之后点NEXT就行了

2. 破解
把 /media/k/MATHWORKS_R2012A/bin/路径下的glnxa64这个文件复制到安装路径/usr/local/MATLAB/R2012A/下的bin文件夹中
在终端输入：

sudo cp /media/k/MATHWORKS_R2012A/bin/glnxa64/* /usr/local/MATLAB/R2012A/bin/glnxa64/ 

cp是复制的意思
接下来启动MATLAB，输入：

cd /usr/local/MATLAB/R2012a/bin/ 
./matlab

由于第一次启动需要激活软件，会出现如下界面

选择”在不使用Internet的情况下手动激活”，点“下一步”

选择破解文件，后缀名是.dat（有的是.lic文件），这个图中的就是license就是.lic选择这个文件，点击“下一步”就可以完成

• 可以先将crack文件夹拷贝到一个固定路径下，输入：

sudo cp /media/k/MATHWORKS_R2012A/crack/* /usr/local/MATLAB/R2012a/ 

复制完成,到时候直接到这个路径下选择破解文件就好了

参考：https://blog.csdn.net/weibo1230123/article/details/77949482

如果找不到有效的license，比如我的license文件到期时间就是2016年双11，忘了从哪儿看的——急着用的话可以直接改一下系统时间，再直接选中/usr/local/MATLAB/R2012a/license里的.lic文件（或者是crack里面的standalone.dat）就能用起来。
——但是，我的电脑改了时间以后，浏览器上不了网了……报告和网络时间不符合，吐血……
所以还是不用这招，可以进入 /usr/local/MATLAB/R2012a/liscenses 打开.lic文件，把里面的代码全部替换为：（注意要有root权限之后输入nautilus，才能开始更改）

尝试启动破解后的matlab 使用命令

 ./matlab

3. 现状
现在我每次开电脑，要在终端输入

sudo su

输入密码后，找到路径：

cd /usr/local/MATLAB/R2012A/bin/
./matlab

就打开MATLAB2012a了。

4. 懒
如果要设置用更少的语句直接打开matlab，好像还要设置环境变量，以及有些人建议设置桌面图标，不过我现在没啥时间了……装好了赶紧跑数据，闲下来再琢磨吧……能用就行……
貌似因为我是在root权限下做的一系列的安装，现在要更改/usr/local/MATLAB/R2012a/下的所有文件都要先获取root权限。有点麻烦，不过同样的……现在没啥时间了……装好了赶紧跑数据，闲下来再琢磨吧……能用就行能用就行……

5.可能会有也可能不会有的后续
关于设置桌面图标和设置全局变量的教程，摘抄一点下来，等哪天不懒了去弄一下：

创建桌面图标
1、 在/usr/share/applications/下创建桌面图标文件：Matlab.desktop（避免你进入目录错误，你可以留意一下，这个文件夹中有很多程序的桌面图标文件×××.desktop）
2、 百度下载一个图标文件，名字命为Matlab.png，放到/usr/local/MATLAB/目录下，编辑Matlab.desktop文件，添加以下内容
[Desktop Entry]
Type=Application
Name=Matlab
GenericName=Matlab 2012A
Comment=Matlab:The Language of Technical Computing
Exec=sh /usr/local/MATLAB/R2012A/bin/matlab
con=/usr/local/MATLAB/Matlab.png
Terminal=false
StartupNotify=true
Categories=Development;Applications;Matlab;
**
3、 保存退出，桌面图标创建OK!
最后一步—->启动
启动之前将matlab的安装文件夹添加到环境变量中，分别修改/ect/profile/文件和用户的~目录下的.bashrc文件，在这两个文件末尾添加上 export PATH=”$PATH:/usr/local/MATLAB/R2012A/bin”
使用命令:source ~/,bashrc　来更新环境变量
现在在终端里输入matlab就可以启动matlab
