class compas.com.MatlabProcess(matlab_exec=None, ws_data=None, ws_filename=None, timeout=None, verbose=True)[source]

Bases: object

Communicate with Matlab through a subprocess.

Parameters

  • matlab_exec (str, optional) – Path to the Matlab executable. Defaults to matlab.

  • ws_data (dict, optional) – Workspace data to be loaded at startup. Defaults to an empty dict.

  • ws_filename (str, optional) – Filename for workspace storage. Defaults to './workspace.mat'.

Examples

>>> m = MatlabProcess()

>>> m.start()
>>> m.write_value('a', 37)
>>> m.run_command('tf = isprime(a);')
>>> m.read_workspace()
>>> m.stop()
>>> print(m.ws_data)

>>> m.write_value('a', 17)
>>> m.run_command('res = isprime(a);')
>>> m.read_value('res')
True

>>> m.run_command('res = isprime(a);', ivars={'a': 17})
>>> m.read_value('res')
True

>>> m.run_command('res = isprime(a);', ivars={'a': 17}, ovars={'res': None})
{'res': True}
