pymatlab Description

Python interface to MATLAB pymatlab lets Python users interface and communicate with MATLAB from Python. This makes it easier for users to migrate from a large MATLAB codebase to Python scripts - one step at a time - by using old MATLAB scripts.Installing:When installing from source distribution revise the include_dir and library_dir.Preparing to use pymatlab:Set the environmental variable LD_LIBRARY_PATH to correct path where pymatlab can find MATLAB's libraries (libmx and libeng) or update /etc/ldconfig. On my system with MATLAB installed in /opt/matlab I have put this line in my .profile:export LD_LIBRARY_PATH=/opt/matlab/bin/glnxa64:/opt/matlab/sys/os/glnxa64:$LD_LIBRARY_PATHUsing pymatlab:First import: >>> from pymatlab.matlab import MatlabSessionInitialise the interpretor, an optional argument is a string to launch matlab: >>> session = MatlabSession() >>> session.close() >>> session = MatlabSession('matlab -nojvm -nodisplay')Create an numpy-array to start the work. >>> from numpy.random import randn >>> a = randn(20,10,30)Send the numpy array a to the MATLAB Workspace to the variable 'A' >>> session.putvalue('A',a)Do something in matlab in MATLAB with variable A. Sucessfull commands return an empty string - if MATLAB generates an error the returning string holds the error message >>> session.run('B=2*A') '' >>> session.run('C') "Error: MATLAB:UndefinedFunction with message: Undefined function or variable 'C'.\n"A trick to make larger scripts more failsafe with regards to syntax errors. Send a script to a string variable and run it with eval(). >>> mscript = """D = A ... for i=1:10 ... D = 2*D ... end ... """ >>> session.putstring('MSCRIPT',mscript) >>> session.run('eval(MSCRIPT)') ''To retrive the variable back to Python: >>> b = session.getvalue('B') >>> (2*a==b).all() TrueDon't forget to close MATLAB. >>> session.close() Requirements: · Python What's New in This Release: · Added the missing MANIFEST.in file to include the docs/ directory. And some small changes in the README.txt to work with restructured text.
