How to run this on Windows? #1

It seems this package doesn't run on windows?

Wow this is prompt reply!

From what I see, only slight changes are necessary for the bridge to work on windows. Here are the error messages:

from pymatbridge import Matlab mlab=Matlab(matlab='/Applications/MATLAB_R2011b.app/bin/matlab') mlab.start() Starting MATLAB Traceback (most recent call last): File "", line 1, in File "C:\Python27\lib\site-packages\pymatbridgeinit.py", line 37, in start self.server_process.start() File "C:\Python27\lib\multiprocessing\process.py", line 130, in start self._popen = Popen(self) File "C:\Python27\lib\multiprocessing\forking.py", line 271, in init dump(process_obj, to_child, HIGHEST_PROTOCOL) File "C:\Python27\lib\multiprocessing\forking.py", line 193, in dump ForkingPickler(file, protocol).dump(obj) File "C:\Python27\lib\pickle.py", line 224, in dump self.save(obj) File "C:\Python27\lib\pickle.py", line 331, in save self.save_reduce(obj=obj, *rv) File "C:\Python27\lib\pickle.py", line 419, in save_reduce save(state) File "C:\Python27\lib\pickle.py", line 286, in save f(self, obj) # Call unbound method with explicit self File "C:\Python27\lib\pickle.py", line 649, in save_dict self._batch_setitems(obj.iteritems()) File "C:\Python27\lib\pickle.py", line 681, in _batch_setitems save(v) File "C:\Python27\lib\pickle.py", line 286, in save f(self, obj) # Call unbound method with explicit self File "C:\Python27\lib\pickle.py", line 748, in save_global (obj, module, name)) pickle.PicklingError: Can't pickle <function _run_matlab_server at 0x046564F0>: it's not found as pymatbridge._run_matlab_server

This is quite obvious, because in windows the file structure is different, and Matlab does not locate in '/Applications/MATLAB_R2011b.app/bin/matlab'.

The good thing is, I can manually start the web server using the .m file in the package. Then using mlab.running I get a True return. So, basically both Python and Matlab are working (independent of platform), while the only problem is a new bridge code for windows.

Actually I like this idea of using Matlab as a webserver. I am using a package of the same spirit. Good luck!

Has development on this stopped? Is there a better solution now for running MATLAB once and making multiple calls from python? I too need a windows solution.
