Graphical User Interface(3/60) Guide > Either click on the Guide Icon on the Matlab-Toolbar or type guide on the command window. > This will open the Quickstart GUI template selection window. Matlab provides a few templates to help with the common GUI design task but these are limited in numbers and you will probably need to start with a blank template. > The initial layout area is usually resizable by clicking and dragging the handles on the corners of the template area.

➢ Either click on the Guide Icon on the Matlab-Toolbar or type guide on the command window. ➢ This will open the Quickstart GUI template selection window. Matlab provides a few templates to help with the common GUI design task but these are limited in numbers and you will probably need to start with a blank template. ➢ The initial layout area is usually resizable by clicking and dragging the handles on the corners of the template area.
