How to set global variables for simulink with matlab functions

60 views (last 30 days)
I'd like to use global variable in matlab function block. But I cannot find "symbols pane" to set global variable as Simulink.Signal object in contents below link site. Could you tell me where it is?
  1. Make sure the Simulink.Signal object is registered to the MATLAB Function block.
  2. In the Modeling tab, in the Design section, click Symbols Pane.
  3. In the Symbols pane, select the data A. This data uses the same name as the global variable. Right click and select Inspect... to open the Property Inspector.
  4. In the Property Inspector, set the Scope of the data to Data Store Memory.
