Hi there,

Trying to have pyhton discover runing Matlab shared session on local Windows desktop... I have a rather special setup where Matlab is actually running using a special user on my desktop. I think i needed to make sure that TMP and TEMP environment variables would point to the same value the Matlab process uses. Still the following does not yield anything but empty string:

import os
import matlab.engine
os.environ["TMP"]='C:\\...' #same path as given by getenv('TMP')
os.environ["TEMP"]='C:\\...' #same path as given by getenv('TEMP')
names=matlab.engine.find_matlab()
print('Matlab names:', names)

Outcome is: Matlab names: ()

despite...

>> matlab.engine.isEngineShared
ans =
       1
>> matlab.engine.engineName
ans =
MATLAB_6248
>>

Help is welcome.

Thanks

Hi Etienne,

'%TEMP%' is the current standard. On the other hand '%TMP%' dates back to time when only DOS existed.

Please find more info here .

I would suggest you to try following steps:

1. Please make sure that MATLAB engine is shared. To do this execute following command at MATLAB command line:

>> matlab.engine.shareEngine

2. Try running following script:

 import os
 import matlab.engine
 #change made here
 os.environ["TMP"]= os.environ["TEMP"];
 #same path as given by getenv('TEMP')
 os.environ["TEMP"]='C:\\...' 
 #To make sure that MATLAB engine is connected.
 #Following should display '2.0'
 eng = matlab.engine.connect_matlab()
 print eng.sqrt(4.0)
 print "\n"
 print matlab.engine.find_matlab()
