Create a python script to simulate a Matlab file and store results?

Question

I have recently started working as a student assistant and I have to write a script in Pycharm (python) which is something new for me. My task is to write a python script which takes a Matlab file (.m file) from the server, execute it and store the results of that file in a different folder. I have created a function which returns the path of the matlab file from the server which I would like to simulate as shown below. def get_next_job() -> Path: host = '127.0.0.1' port = 2000 with socket.socket(socket.AF_INET, socket.SOCK_STREAM) as s: s.connect((host, port)) s.sendall(json.dumps({"task_name": "next_simulation_file", "host_name": socket.gethostname()}).encode()) received = s.recv(1024) m = received.decode() message = json.loads(m) return Path(message["next_simulation_file"]) Now, my question is how do I initialize matlab from python to simulate this file and store the results somewhere. I would really appreciate the help.

Answer 1

import socket

import json

from pathlib import Path

import matlab.engine

def get_next_job() -> Path:

host = '127.0.0.1'

port = 2000

with socket.socket(socket.AF_INET, socket.SOCK_STREAM) as s:

s.connect((host, port))

s.sendall(json.dumps({"task_name": "next_simulation_file", "host_name": socket.gethostname()}).encode())

received = s.recv(1024)

message = json.loads(received.decode())

return Path(message["next_simulation_file"])

def run_matlab_simulation(matlab_file: Path, result_dir: Path):

# Start MATLAB engine

eng = matlab.engine.start_matlab()

# Change directory to the MATLAB file location

eng.cd(str(matlab_file.parent))

# Get the MATLAB file name without the extension

matlab_filename = matlab_file.stem

# Run the MATLAB file and save results

result_path = result_dir / f"{matlab_filename}_results.mat"

eng.eval(f"{matlab_filename}; save('{result_path}')", nargout=0)

print(f"Simulation completed. Results saved at: {result_path}")

# Stop MATLAB engine

eng.quit()

if __name__ == "__main__":

# Get the next MATLAB job file

matlab_file_path = get_next_job()

# Define the result storage directory

results_directory = Path("path/to/results") # Update this path accordingly

results_directory.mkdir(parents=True, exist_ok=True)

# Run MATLAB simulation

run_matlab_simulation(matlab_file_path, results_directory)
