Introduction
MATLAB enjoys extensive adoption in universities and research laboratories for both introductory and advanced coursework spanning mathematics, the natural sciences, and particularly engineering disciplines. In the industrial sector, the environment supports research, development, and product design. The core MATLAB environment provides a comprehensive suite of built-in functions and toolboxes, allowing users to tackle a broad array of standard analytical and computational challenges.
MATLAB Windows
1. Command Window
This is where you directly enter commands, perform calculations, or run scripts. It acts as the main interactive area for executing MATLAB code line-by-line.
2. Command History
This window keeps a record of all previously entered commands. You can re-run or copy past commands from here without retyping them.
3. Workspace
Displays all the variables currently stored in memory. You can see variable names, sizes, and values and double-click to inspect or edit them.
4. Editor
Used to write, edit, and save scripts or function files (e.g., `.m` files). It provides features like syntax highlighting and debugging tools.
5. Current Folder
Shows files and folders in the current directory. You can use this window to manage files and open scripts or data for your project.
6. Figure Window
This window displays graphical output such as plots, charts, or images generated using MATLAB commands like plot() or imshow().
7. Command Toolbar
A set of buttons that provides quick access to common actions like saving, opening, debugging, and running scripts.
8. Help Browser
Provides documentation and help topics on MATLAB functions, toolboxes, and usage examples. Very useful for learning and troubleshooting.
