- 5. 5 Matlab Structure Matlab Command Line (Interactive Mode) m-files (Batch Mode functions mat-files Command execution like DOS command window Series of Matlab commands Data storage/ loading
- 6. 6 Main Matlab Window This sub window lists all variables that you have generated so far along with there type and size. Workspace All commands typed on MATLAB prompt in the command window get recorded, even across multiple session in this window. Command History The main window characterized by the MATLAB command prompt (>>) Command Window This is where you write, edit, create, and save your own script or programs in files called m-files. Editor Window This is where all your files from the current directory are listed. Current Directory
- 8. 8 Matlab as calculator • As an example of a simple interactive calculation, just type the following expression 1 + 2 × 3 at the prompt command >> • Press Enter. • The last calculation overwrites the previous calculation in ans.
