How to unfix the seed with Matlab engine?

I'm try to use random function in a Matlab function which is called by a python program. Unfortunately, the seed seems to be fixed by the matlab engine because the function called in Matlab works, but when it is called through Python it always returns the same values.
I isolated the problem by calling several times this python program :
import matlab.engine
import random
if __name__ == "__main__":
# Start matlab
eng = matlab.engine.start_matlab()
print(random.random())
print(eng.rand(1, 1, nargout=1))
# Close Matlab
eng.quit()
I obtained different values for the python random function, but the value for the Matlab function is always the same. I use Matlab 2015a and python 2.7.

Every time you call matlab.engine.start_matlab you're starting a new MATLAB process. See this documentation page for how to "Generate Random Numbers That Are Different".
