Python calls matlab.double, which is a very simple line of code, but it can be seen from the task manager that the memory has been soaring.I'm using a for loop to call this code constantly, and I'm also using some clear and other functions to clear the memory, but none of them have any effect unless the instance is restarted
import matlab.engine
test_matlab_engine = matlab.engine.start_matlab('-nodisplay -singleCompThread -nojvm')
def a():
data_array = []
for i in range(10000):
data_array.append(i)
a= matlab.double(data_array)
if __name__ == '__main__':
while True:
a()

Facing the same issue and still trying to debug. Using Python 3.10 and Matlab 2023b

I'm in the same environment, and my final solution was to generate the .mat file, and matlab goes and reads the .mat file without variables to interact with.
My guess is that there is a memory leak in matlb.engine, but I don't really have a solution at the moment.
