環境:matlab2014b,mac os,python 2.7html
1. windows用戶能夠用win32com,COM只適用於WINDOWS系統,這裏沒有嘗試。python
2. 若是是執行簡單的命令,能夠用matlab2014b提供的引擎,個人在/Applications/MATLAB_R2014b.app/extern/engines/python。linux
###Matlab Engine for Python
#Call Matlab Function from Python
------------------------------
##Step 1: Installation
#Install with Administrator Privileges
cd "matlabroot\extern\engines\python"
python setup.py install
#Install without Administrator Privileges
cd "matlabroot\extern\engines\python"
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)
------------------------------git
3. python直接調用執行matlab,現有不少工具:github
3.1. pymatwindows
沒有python2.7的支持api
3.2. pymat2app
在pymat基礎上改良過的。python2.7
3.3. mlabwrapasync
http://mlabwrap.sourceforge.net/
須要用root權限。最初安裝不成功,報OSError: [Errno 2] No such file or directory,應該是找不到MATLAB2014b的路徑,更改PATH加上MATLAB的安裝目錄後成功(在setup.py中更改安裝參數應該也能夠,沒有嘗試)。export PATH=/Applications/MATLAB_R2014b.app/bin:$PATH
from mlabwrap import mlab的時候又報import mlabraw引入不成功,google以後發現export DYLD_LIBRARY_PATH=/Applications/MATLAB_R2014b.app/bin/maci64:$DYLD_LIBRARY_PATH便可,
這裏runmodel.m文件內容是Function result = runmodel() ..... END
調用方式爲mlab.runmodel()
解決方案參考了http://stackoverflow.com/questions/13311415/run-a-matlab-script-from-python-pass-args/13316939#13316939
http://sourceforge.net/p/mlabwrap/mailman/message/26145026/
傳入參數:
mlab.runmodel('[1,2,3,4,5]',...)注意參數必須爲字符串,python會將其轉換爲各類形式。
3.4. mlab
貌似在mac上不穩定,執行不了後就放棄了。
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
