Syntax

name = getGlobalNamesImpl(obj)

Description

name = getGlobalNamesImpl(obj) specifies the names of global variables that are declared in a System object™ for use in a Simulink® P-code file. For P-code files, in addition to declaring your global variables in stepImpl, outputImpl, or updateImpl, you must include the getGlobalNamesImpl method. You declare global variables in a cell array in the getGlobalNamesImpl method. System objects that contain these global variables are included in Simulink using a MATLAB System block. To enable a global variable in Simulink, your model also must include a Data Store Memory block with a Data Store Name that matches the global variable name.

getGlobalNamesImpl is called by the MATLAB System block.

Note

You must set Access = protected for this method.

Input Arguments

obj

System object

Output Arguments

name

Name of the cell array containing the global variable names. The elements of the cell array are character vectors.

Examples

Specify two global names in your class definition file.

methods(Access = protected)
    function glnames = getGlobalNamesImpl(obj)
      glnames = {"FEE","OTHERFEE"};
    end
    
    function y = stepImpl(obj,u)
      global FEE
      global OTHERFEE
      y = u - FEE * obj.lastData + OTHERFEE;
      obj.lastData = u;
    end
end
