这里由于开发一个matlab版本的API数据接口需要，经过matlab，的urlread、webread以及私人写的urlread2的无限折磨后依然决定放弃，继续用matlab写api接口。matlab的版本是2016b，据说2015版本以上才行，没有亲自试过（前提是在已安装组件包含python，查看方式matlab根目录/extern/engines/python）。
主要参考：matlab的官方帮助文档
基本
1.版本信息已经更改python版本
查看版本信息这里默认Python的环境变量设置是3.5版本（仅仅支持3.5、3.4、2.7）
>> pyversion
version: '3.5'
executable: 'C:\software\python3\python.EXE'
library: 'C:\software\python3\python35.dll'
home: 'C:\software\python3'
isloaded: 0
下面改下默认环境变量，我这里Python2和python3同时存在一个目录下，环境变量设置了一个PYTHON_HOME:仅仅改下这里即可，方便省事。matlab需要重启才能生效！！！

>> pyversion
version: '2.7'
executable: 'C:\software\python2\python.EXE'
library: 'C:\Windows\system32\python27.dll'
home: 'C:\software\python2'
isloaded: 1
2.调用Python的module的方法或函数
调用Python的module很简单
import py.numpy.arange %不建议
x = arange(3)；
cal = py.calendar.TextCalendar; %建议方法
% 重点是在于调用自定义的函数或者方法，并不能直接采用上面的方法
py.sys.path % 查看Python的module搜寻路径
>> count(py.sys.path,'')
ans =
int64
1 % 已经添加当前目录，matlab从1开始计算index
>> insert(py.sys.path, int32(0), 'D:\PycharmProjects\SupwinPython2\API') %插入指定的目录
%在该目录下创建了一个matlab.py文件
%a = 1
%b = 2
%c = a + b
>> py.matlab.a
ans =
int64
1
>> py.matlab.c
ans =
int64
3
实例
- 版本
matlab版本 > =2015a
python = 2.7/3.4 / 3.5
- 环境变量设置
需要在windows path中配置好对应Python的环境变量
example:
PYTHON_HOME: C:\software\python2
path中添加：%PYTHON_HOME%\Scripts、%PYTHON_HOME%\、%PYTHON_HOME%\Lib\
