I am trying to execute "sim_profiles.m" which has several dependencies such as Parallel computing toolbox(parfor), LIONSIMBA(Simulation library written as Matlab). I referenced a document, "Get Started with MATLAB Engine API for Python". This is what I have tried:
import numpy as np
import matlab.engine
eng = matlab.engine.start_matlab()
fitness, measured_data = eng.sim_profiles(1, 1, arr_data, 100)
print(fitness, measured_data)
It printed the followed exception
MatlabExecutionError:
File C:\Users\user\Desktop\LIONSIMBA\LIONSIMBA-master\LIONSIMBA-master\battery_model_files\simulator_tools\differentialInitialConditions.m, line 33, in differentialInitialConditions
File C:\Users\user\Desktop\LIONSIMBA\LIONSIMBA-master\LIONSIMBA-master\startSimulation.m, line 226, in mainCore
File C:\Users\user\Desktop\LIONSIMBA\LIONSIMBA-master\LIONSIMBA-master\startSimulation.m, line 112, in startSimulation
File C:\Users\user\Desktop\강화학습\pytorch-soft-actor-critic-SAC_V\pytorch-soft-actor-critic-SAC_V\sim_profiles.m, line 36, in sim_profiles
Integers can only be combined with integers of the same class, or scalar doubles.
I already tested "sim_profiles.m" code in MATLAB and it works without any error.

I solved this problem with this link. I guess Matlab did not apply implicit casting to variables from Python. The following code works perfectly.
fitness, measured_data = eng.sim_profiles(1, 1, matlab.double(arr_data), matlab.double([100]))
