Using Simulink

Creating Annotations Programmatically

You can use the Simulink add_block command to create annotations at the command line or in an M-file program. Use the following syntax to create the annotation:

• add_block('built-in/Note','path/text','Position', [center_x, 0, 
  0, center_y]); 
  

where path is the path of the diagram to be annotated, text is the text of the annotation, and [center_x, 0, 0, center_y] is the position of the center of the annotation in pixels relative to the upper left corner of the diagram. For example, the following sequence of commands

• new_system('test')
  open_system('test')
  add_block('built-in/Gain', 'test/Gain', 'Position', [260, 125, 
  290, 155])
  add_block('built-in/Note','test/programmatically created', 
  'Position', [550 0 0 180])
  

creates the following model:

To delete an annotation, use the find_system command to get the annotation's handle. Then use set_param to set the annotation's Name property to the empty string, e.g.,

• h = find_system('test', 'FindAll', 'on', 'Type', 'annotation');
  set_param(h, 'Name', '');
