Customize System Objects for Simulink

Customize System object™ for use inMATLAB Systemblock

TheMATLAB Systemblock enables a System object defined in MATLAB^®to be used as a block in Simulink^®. To control the block appearance or output, or to enable System object usage in a For Each subsystem, use the provided implementation methods to customize your System object. For more information about defining a System object, seeDefine Basic System Objects(MATLAB) orSystem Objects(MATLAB).
