Changing Note Properties

You can use the Note properties dialog box to edit note properties.

The Note properties dialog box contains the following properties:

Field	Description
Label	The label for the note. This includes the name of the note and its associated actions.
Description	Textual description/comment.
Use display text as click callback	Checking this option causes a Simulink model to treat the text in the Text field as the note's click function. The specified text must be a valid MATLAB expression comprising symbols that are defined in the MATLAB workspace when the user clicks this annotation. Selecting this option disables the ClickFcn edit field.
ClickFcn	Specifies MATLAB code to be executed when a user single-clicks this annotation. The model stores the code entered in this field.
Document link	Enter a URL address or a general MATLAB command. Examples are www.mathworks.com, mailto:email_address, and edit /spec/data/speed.txt.

See Annotation Callback Functions in the Simulink documentation for a description of the ClickFcn edit field.

TeX Instructions

In the preceding procedure, note a third selection of the Text Format submenu called TeX instructions. This selection enables you to use a subset of TeX commands embedded in the string to produce special characters. For example, you can embed Greek letters and mathematical symbols.

5. Replace the existing note text with the following expression.

   \it{\omega_N = e^{(-2\pii)/N}}
