How to Load Demo Data

For MAT files, the easiest way to load demo data is using the Load Dialog Box:

1. From the file menu Load Data (or Import Workspace/MAT File).
2. When the dialog box appears click the From File button.
3. Type the name of the demo MAT file to loaded and hit the return key.
4. Select the variables to be loaded and click the Load button.
