The Command Window in Matlab is a versatile interface for executing commands, testing code, and learning new concepts. To use it, simply type a command or expression, press Enter, and Matlab will display the result immediately. This real-time interaction allows users to experiment with different functions and concepts effectively.

The Command Window serves as a powerful debugging tool. By testing individual lines of code or inspecting variables directly, you can identify and resolve issues quickly. This makes the Command Window an essential feature for both beginners and experienced users.
