环境：matlab2014b，mac os，python 2.7
1. windows用户可以用win32com，COM只适用于WINDOWS系统，这里没有尝试。
2. 如果是执行简单的命令，可以用matlab2014b提供的引擎，我的在/Applications/MATLAB_R2014b.app/extern/engines/python。
###Matlab Engine for Python
#Call Matlab Function from Python
------------------------------
##Step 1: Installation
#Install with Administrator Privileges
cd "matlabrootexternenginespython"
python setup.py install
#Install without Administrator Privileges
cd "matlabrootexternenginespython"
python setup.py build --build-base builddir install --install-base installdir
Include 'installdir' in the search path for Python packages
Add 'installdir' to the PYTHONPATH environment variavle
------------------------------
##Step 2: Using Matlab Engine
#Start and quit
import matlab.engine
eng = matlab.engine.start_matlab()
eng.quit()
#Call Matlab Functions:
#Just call with form eng.xxx()
#the function xxx should in the namespace of matlab.
#Asynchronously Call
import matlab.engine
eng = matlab.engine.start_matlab()
future = eng.sqrt(4.0,async=True)
ret = future.result()
print(ret)
#WorkSpace Usage:
import matlab.engine
eng = matlab.engine.start_matlab()
eng.workspace['y'] = x
a = eng.eval('sqrt(y)')
print(a)
#Skills for unsupported features in python
#eng.eval()
import matlab.engine
eng = matlab.engine.start_matlab()
eng.eval("T = readtable('patients.dat');",nargout=0)
#Plot With Matlab:
import matlab.engine
eng = matlab.engine.start_matlab()
data = eng.peaks(100)
eng.mesh(data)
------------------------------
3. python直接调用执行matlab，现有很多工具：
3.1. pymat
没有python2.7的支持
3.2. pymat2
在pymat基础上改良过的。
3.3. mlabwrap
http://mlabwrap.sourceforge.net/
需要用root权限。最初安装不成功，报OSError: [Errno 2] No such file or directory，应该是找不到MATLAB2014b的路径，更改PATH加上MATLAB的安装目录后成功（在setup.py中更改安装参数应该也可以，没有尝试）。export PATH=/Applications/MATLAB_R2014b.app/bin:$PATH
from mlabwrap import mlab的时候又报import mlabraw引入不成功，google之后发现export DYLD_LIBRARY_PATH=/Applications/MATLAB_R2014b.app/bin/maci64:$DYLD_LIBRARY_PATH即可，
这里runmodel.m文件内容是Function result = runmodel() ..... END
调用方式为mlab.runmodel()
解决方案参考了http://stackoverflow.com/questions/13311415/run-a-matlab-script-from-python-pass-args/13316939#13316939
http://sourceforge.net/p/mlabwrap/mailman/message/26145026/
传入参数：
mlab.runmodel('[1,2,3,4,5]',...)注意参数必须为字符串，python会将其转换为各种形式。
3.4. mlab
貌似在mac上不稳定，执行不了后就放弃了。
3.5. python-matlab-bridge
https://github.com/jaderberg/python-matlab-bridge
only work on unix, and is based on TCP transmission while messages are decoded in JSON format。
3.6. Nipype
