Calling Matlab configuration in pycharm: No module named 'matlab.engine'; 'matlab' is not a package

使用Pycharm配置调用matlab经验分享,Read the post summed up,Mainly the article：python调用matlab的方法记录

matlab2018b支持python3.5、3.6但是不支持python3.7.如果遇到不匹配的情况,记得把python的版本降低,或者安装更新版本的matlab,比如:matlab2020b

1. 首先找到matlab安装路径,我的路径在：D:\matlab2020b\extern\engines\python,如下：
This is after the success of the installation directory

2. 利用命令行,cmd,到D:\matlab2020b\extern\engines\python文件夹下,然后依次执行下面命令.

python setup.py build --build-base="builddir" install
 
python setup.py install --prefix="installdir"
 
python setup.py build --build-base="builddir" install --prefix="installdir"
 
python setup.py install --user

例如：

After the success of the installation using the following code to test whether can run：

import matlab.engine
from numpy import *

if __name__ == '__main__':
    eng = matlab.engine.start_matlab('MATLAB_R2019b')
    A = matlab.double([[1, 2], [5, 6]])
    print(type(A), A.size, A)
    print(eng.eig(A))
    eng.quit()
    pass

如果测试报错：No module named ‘matlab.engine’; ‘matlab’ is not a package

记得查看pythonThe interpreter paths are generated insidematlab文件,例如下面的图片：
D:\python3.7\venv\Lib\site-packages\matlab

如果没有,那么把D:\matlab2020b\extern\engines\python下的dist中的matlab文件复制python解释器路径.

如果还是报错,可能的原因如下：

1.Copy the wrong path,检查python解释器路径.
2.D:\matlab2020b\extern\engines\python路径下的matlab的包错误,导致出现问题.Reinstall or directly to find an already installedmatlab复制到python解释器路径.

python里调用matlab脚本,参考：参考
matlab中编写：

function hellomatlab()

clear
sum = 0;
for i = 1:100
   sum = sum +i;
   disp(['sum=',num2str(sum)]);
end

pycharm中编写：

import matlab
import matlab.engine
engine = matlab.engine.start_matlab()  # 启动matlab engine
engine.hellomatlab(nargout = 0)

注意：matlab代码和pythonCode needs to be in the same directory
调用结果：
