python 调用matlab

1.安装matlab engine api

Build in Nondefault Folder, Install in Default Folder

If you do not have write permission to build the engine in the MATLAB® folder, use a nondefault folder, builddir.

cd "matlabroot\extern\engines\python"
python setup.py build --build-base="builddir" install

 

2.调用引擎

• Start Python® at the operating system prompt.

• Import the matlab.engine package into your Python session.

• Start a new MATLAB® process by calling start_matlab. The start_matlab function returns a Python object, eng, which allows you to pass data and call functions executed by MATLAB.

import matlab.engine
eng = matlab.engine.start_matlab()

 

3.调用m文件

In your current folder, create a MATLAB script in a file named triarea.m.

b = 5;
h = 3;
a = 0.5*(b.* h)

After you save the file, start Python and call the script.

import matlab.engine
eng = matlab.engine.start_matlab()
eng.triarea(nargout=0)

a =

    7.5000

Specify nargout=0. Although the script prints output, it returns no output arguments to Python.

这种方法没有返回值。如果要返回值，将m文件改写为函数形式

function a = triarea(b,h)
a = 0.5*(b.* h);
