python调用matlab脚本
一、MATLAB 安装部署
软件智库-Matlab 2018a中文版软件下载和安装教程
博客园-MATLAB R2019b超详细安装教程（附完整安装文件）
本人使用的第二种。
二、Python调用Matlab方法以及测试程序
1、python测试代码
import matlab.engine
import pymysql
print("start matlab engine...")
eng = matlab.engine.start_matlab()
print("matlab engine is start!")db = pymysql.connect("127.0.0.1", "root", "123456", "test", charset='utf8')
cursor = db.cursor()
sql = "SELECT * FROM usertb"
try:
cursor.execute(sql)
results = cursor.fetchall()
for row in results:
y = eng.calc_area(row[0],row[1])
print(y)
except:
print "Error: unable to fecth data"db.close()2、数据库 可以不用数据库，直接在python中调用matlab函数即可！
--
-- 表的结构 `usertb`
--CREATE TABLE `usertb` (
`id` bigint(20) UNSIGNED NOT NULL,
`uname` varchar(20) DEFAULT NULL,

-- 转储表的索引
----
-- 表的索引 `usertb`
--
ALTER TABLE `usertb`
ADD UNIQUE KEY `id` (`id`);
3、matlab测试代码
functions = calc_area(w,h)
s = "ID:" + w + " 姓名：" + h;
end4、注意事项 python 版本 2.7
matlab 代码需放到python项目中
5、程序运行结果 【python调用matlab脚本】
