CANCELED Python 3 support

Better make a new library for Python 3 with the following properties:

CANCELED Auto-convert int to float in matlab.put()

Canceled: “Explicit is better than implicit”

The problem is that in MATLAB this conversion is implicit and writing e.g.

matlab.put(‘a’, 1) # <- here ‘a’ will be int

may lead to unexpected behaviors.

Could be activated via by a parameters:

matlab = matlab_wrapper.MatlabSession(auto_int_conversion=True)

Make sure that the MATLAB process is gone in __del__()

  • add `matlab._pid’ (use features(‘getpid’) in MATLAB, might not exist in older versions)
  • check the standard library for the best kill/terminate functions

MATLAB is unresponsive during execution of svd(). I did not find a way to reasonably kill the process (in destructor), because it hangs in the engClose().

m.workspace.svd(np.zeros((10000,10000)))
### Get MATLAB PID
try:
    pid = self.workspace.feature('getpid')
    self._pid = int(pid)
except RuntimeError:
    self._pid = None

Check for /bin/csh on Linux

/bin/csh is required by libeng and the lack of it could be detected by matlab_wrapper.

lib_dir = join(matlab_root, “bin”, “win32”)

CANCELED Investigate `undefined symbol’ error

Canceled: not able to reproduce.

Might have something to do with matplotlib.

Eventually put in FAQ.

Investigate indexing in Numpy and MATLAB

https://groups.google.com/forum/#!topic/matlab_wrapper/wAp6veM6xgY

Numpy indexing comes form C.

In carr[i][j][k], k iterates the most inner row arrays.

arr.ravel(‘K’) flattens array in the order the elements occur in the memory.

matlab_wrapper has to take into account inverse indexing:

[i][j][k][l] <=> [l][k][j][i]

as well as row vs column of the inner most arrays:

[i][j][k][l] <=> [k][l][j][i]

  • backward compatibility is super important
  • possible solution is to disable squeeze’ing in a backward compatible way, e.g., MatlabSession(squeeze=False)
