Yes, MATLAB 2018b is compatible with Oracle Database version 12.2.0.2. MATLAB connects to databases using the Database Toolbox, which utilizes JDBC (Java Database Connectivity) for database connections.
To connect MATLAB to Oracle, you need to install the appropriate JDBC driver. Since MATLAB R2018b uses JDK version 8, it should support connections to Oracle 12c. For more information on setting up the database driver and data source, you can refer to this documentation page: https://www.mathworks.com/help/database/ug/configure-driver-and-data-source.html.
Once you have the JDBC driver installed correctly, you can use the functions in the Database Toolbox to establish a connection to your database.
