Jupyter和MATLAB关联：windows系统

作者：韩少真(西北大学) || 展金永（对外经济贸易大学）

1. 准备工作-关联前提

首先，请按助教提供教程安装Anaconda和MATLAB，并检验Anaconda和MATLAB是否已经成功安装在本机电脑上。

2. 安装matlab的python拓展

2.1 获取扩展的路径

打开matlab的安装路径（如果忘记可以看下matlab安装教程的第六步），依次打开extern、engines、python文件夹，进入python文件夹。然后点击地址栏，复制python文件夹的路径地址，如下图所示：

我的电脑为D:\Polyspace\R2019a\extern\engines\python，根据matlab安装的地址不同，D:\Polyspace\R2019a\可能有所差异，请根据个人安装状况更改。

2.2 安装MATLAB的Python扩展

• 通过开始-Anaconda3（64-bit）-Anaconda Powershell prompt，打开Anaconda Powershell prompt。如果直接打开执行下面的操作无法正常关联python和matlab，则需要右击选择以管理员身份运行，重新进行接下来的操作。
  
• 在powershell中依次输入以下命令并按回车键执行

cd "D:\Polyspace\R2019a\extern\engines\python"
python setup.py install

-执行结果如下所示，表明扩展安装成功

3.在Python中安装matlab_kernel包

• 根据下图，打开Anaconda prompt
  
• 在Anaconda prompt中运行以下代码

pip install matlab_kernel

• anaconda
  会自动安装matlab_kernel包，具体如下所示，则安装成功

(base) C:\Users\mailshaozhen>pip install matlab_kernel

• 然后在Anaconda prompt中输入jupyter notebook，回车执行就会直接打开jupyter notebook。打开jupyter notebook的方法有很多，可以在开始程序中找到jupyter notebook点击打开，也可以到Anaconda的主界面打开jupyter notebook。根据下图步骤新建Matlab的文档。
  

  

• 在打开的notebook中输入matlab语句，例如a=3，表示生成新变量a，并给其赋值为3。点击运行，出现运行结果，表明关联成功。具体如下图所示：

• 注意：执行第一条指令的时候要耐心等一等，matlab r2019a程序比较大，启动比较慢，执行完第一行执行，接下来执行就会快很多，可以继续执行b=a，测试发现基本不用等待就会出结果。
