The error you encountered suggests that there might be an issue with launching MATLAB using the matlab.engine module in Python. This error can occur due to various reasons, such as compatibility issues or incorrect installation.

To troubleshoot this issue, you can try the following steps:

1. Ensure that you have installed the correct version of the MATLAB Engine API for Python that is compatible with MATLAB R2023b and your Macbook M1 architecture. You can check the MathWorks website or contact their support to confirm the compatibility.
2. Verify that MATLAB R2023b is installed correctly on your Macbook M1. Make sure you can launch MATLAB directly from the MATLAB application.
3. Check if the MATLAB engine API is properly installed and accessible from your Python environment. You can try importing the matlab.engine module without starting MATLAB to see if it throws any errors.
4. If the issue persists, try reinstalling the MATLAB Engine API for Python. Follow the installation instructions provided by MathWorks carefully and ensure that you are using the correct installation method for your system.
5. If you are using a virtual environment in Python, make sure the environment is activated and the MATLAB Engine API is installed within that environment.

• my matlab version is R2023b and my python version is 3.11

Verify that MATLAB R2023b is installed correctly on your Macbook M1. Make sure you can launch MATLAB directly from the MATLAB application.

• working is working perfectly

Verify that MATLAB R2023b is installed correctly on your Macbook M1. Make sure you can launch MATLAB directly from the MATLAB application.

• I think it is installed properly

If the issue persists, try reinstalling the MATLAB Engine API for Python. Follow the installation instructions provided by MathWorks carefully and ensure that you are using the correct installation method for your system.

• tried, still throwing the same error

If you are using a virtual environment in Python, make sure the environment is activated and the MATLAB Engine API is installed within that environment.

• both are done

Do you have suggestions on what can be done next?
