Hi Akash,

I understand that you want to export data from Simulink to a database to use it further into a Machine Learning model.

To input data from a Simulink model into a database, you can use the Database Toolbox in MATLAB. Here is a general approach to accomplish this:

1. Connect to the database: Use the `database` function to establish a connection to your database. Provide the necessary details such as the database name, username, password, and other connection parameters.

conn = database(dbName, username, password, driver, url);

2. Prepare the data: Extract the required data from your Simulink model and format it appropriately to match the database schema. You can use MATLAB functions to preprocess and organize the data as needed.

3. Insert data into the database: Use the `exec` function to execute an SQL query to insert the data into the database. Construct the SQL query based on the table structure and the data you want to insert.

insertQuery = sprintf('INSERT INTO tableName (column1, column2, ...) VALUES (%s, %s, ...)', value1, value2, ...);
    
exec(conn, insertQuery);

4. Close the database connection: After inserting the data, it is good practice to close the database connection to release system resources.

close(conn);

By following these steps, you can input data from your Simulink model into a database using the Database Toolbox in MATLAB. Make sure to replace `dbName`, `username`, `password`, `driver`, `url`, `tableName`, `column1`, `column2`, etc., with the actual names and values specific to your database setup.

Refer to the following video to know more about Database Toolbox in MATLAB:

Refer to the following MATLAB documentation for ‘exec’ and ‘database’ functions:

Hope the above solution helps.
