Description

Use the matlab.system.display.Header class to specify the content of the header in the Block Parameters dialog box for a MATLAB System block. The header includes a title and descriptive text. You can also include a link to the code that defines the System object™ for the block.

Create an instance of this class within the getHeaderImpl method for the block.

Creation

Description

h = matlab.system.display.Header creates an instance of the Header class.

h = matlab.system.display.Header(Name,Value) creates an instance of the Header class with property values defined using one or more name-value arguments.

h = matlab.system.display.Header(sysObj) creates an instance of the Header class and configures the properties based on the System object sysObj.

h = matlab.system.display.Header(sysObj,Name,Value) creates an instance of the Header class and configures properties based on the System object sysObj and one or more name-value arguments. The name-value arguments you specify override the property values that come from the System object.

Input Arguments

expand all

System object for MATLAB System block, specified as a System object. When you specify a System object as the input for the Header class constructor, the instance created by the constructor has properties set based on the System object.

  • Title — System object name

  • Text — Help summary for System object

  • ShowSourceLink — true unless the System object code is P-coded so that the source code is not available

You can specify this argument as mfilename('class').

Define a header in your class definition file.

 methods (Static, Access = protected)
    function header = getHeaderImpl
       header = matlab.system.display.Header(mfilename('class'), ...
           'Title','AlternativeTitle',...
           'Text','An alternative class description');
    end
 end

The header appears above the Parameters section in the Block Parameters dialog box. This example creates a header that includes a link to the source code.

The Block Parameters dialog box for a MATLAB System block has a header with the title AlternativeTitle, the text "An alternative class description," and a link to the source code.
