when I define a variable to be used in Simulink in an m file (action1 and action2 are predefined)
% action1=1
% action2=2
set_param('try11/Constant2','Value','action2')
set_param('try11/Constant','Value','action1')
sim('try11.slx')
s1=try11/Constant
no error is reported and the simulation is started. try11 is just a simple Simulink file adding "Constant2"(action2) and "Constant" (action1). However when I try to run the following in Python.
eng = matlab.engine.start_matlab()
eng.workspace['action2'] = matlab.double([0.0])
eng.workspace['action1'] = matlab.double([1.0])
eng.tryy(nargout=0)
reward = eng.eval('ans.output')
print(reward)
I get the following error.
Error using tryy (line 3)
