操作指南 简单说明 我安装的是MATLAB2022a和Python3.8.6安装时请勾选所有可以勾选的包括路径。对应版本安装完成后在MATLAB命令行中敲入执行路劲’D:\SoftwareApps\Python3_7\python.exe’因人而异
pyenv(Version,D:\SoftwareApps\Python3_7\python.exe)完了以后执行下面的操作
pe pyenv;
pe.Version完成后的界面为 因为MATLAB更多的是矩阵计算我们需要安装两个库一个是numpy一个是scipy。具体地我们可以在windows 的操作终端(cmd/terminal)输入python进入到python可以执行的页面执行以下命令
import sys
import subprocess
subprocess.check_call([sys.executable, -m, pip, install,numpy])
subprocess.check_call([sys.executable, -m, pip, install,scipy])完成之后我们即可开始测试

# -*- coding: utf-8 -*-Code that demonstrates how to run Python code from MATLAB
This is the Python code that is called from MATLAB
Author: Aleksandar Haber
Date: December 2022The matrices A and B are passed to Python from MATLAB
The list ReturnList is returned to MATLAB# You should run these code lines in a separate Python session if the libraries numpy and scipy are not installed
# import sys
# import subprocess
# subprocess.check_call([sys.executable, -m, pip, install,numpy])
# subprocess.check_call([sys.executable, -m, pip, install,scipy])import numpy as np
from scipy import linalgC1 A B
C2 np.matmul(A,B)
C3 np.eye(param1,param1)
C4 linalg.inv(A)# this list is returned to MATLAB and later on unpacked in MATLAB
