Hi Meri,

I understand that you are facing the error -"Error using builtin: Cannot find builtin function 'handle'", while plotting using the plot function. This error could be due to an issue with the graphics system or the handle graphics functionality in MATLAB.

To resolve this problem, you can try the following steps:

1. Restarting MATLAB can help resolve temporary issues related to the graphics system. Close MATLAB, then reopen it and try running the code again to see if the problem persists.
2. Verify that the MATLAB path is correctly set to include all the necessary folders and directories. This ensures that MATLAB can find all the required functions and built-in components.

Hope this solves your query.
