MATLAB Windows  Command Window  Workspace  Command History  Editor Window

1. Command Window  It is the main window where you type commands directly to the interpreter.  It can show you errors when you debug MATLAB files. (e.g. type of error or location of error)

Examples for applications:  1. Save data  2. View data value  3. Plot figures

2. Workspace  Current Directory ----your work need to be processes in one directory  Workspace ----show you the name of each variable and its size

3. Command History  Show you a lot of statements which were recently used in the command window
