Python opening multiple thread of matlab

[Stefan Schukat]

Hello, 

you just forgot to initialize the COM runtime for the separate thread. 
try following:

    def __init__(self,matlab_command):
        self.matlab_command = matlab_command
        threading.Thread.__init__(self)
 
    def run(self):
	  import pythoncom
	  pythoncom.CoInitialize()
        try:
		matlab_object = Dispatch('matlab.application.single')
            execute = getattr(matlab_object,'Execute')
            execute(self.matlab_command)
        finally:
            matlab_object = None
            pythoncom.CoUnitialize()
