Implement Blocks with System Objects
MATLAB System block uses System object to implement MATLAB® algorithms in Simulink. Before you begin using a MATLAB System block, you must have a System object to associate with a block. A System object is a special kind of MATLAB class and they are designed specifically for the implementation and simulation of dynamic systems.

| MATLAB System | Include System object in model |
Examples and How To
Implement a MATLAB System Block
Implement a block and assign a System object to it.
Change Blocks Implemented with System Objects
Implement a block with another System object.
Specify Sample Time for MATLAB System Block
The sample time of a block is a parameter that indicates when the block produces an output, and eventually updates its internal state.
Call Simulink Functions from MATLAB System Block
Learn to call a Simulink function from a MATLAB System block
Change Block Icon and Port Labels
Change the icon appearance of your block.
Add and Implement Propagation Methods
To define output specifications, use propagation methods.
Use System Objects in Feedback Loops
Process nondirect feedthrough data through the System object.
Share data between MATLAB System and other blocks using the
global keyword and the Data Store Memory
block or Simulink.Signal object.
Concepts
Implement your own algorithms using System objects.
Mapping System Object Code to MATLAB System Block Dialog Box
The System object source code controls the appearance of the block dialog box.
You can use MATLAB System block in Simulink models for simulation via interpreted execution or code generation.
Simulink Engine Interaction with System Object Methods
Follow a process view of the order in which the MATLAB System block invokes System object methods within the context of the Simulink engine.
Nonvirtual Buses and MATLAB System Block
Use nonvirtual buses as input and output signals
Share data between MATLAB System and other blocks using the
global keyword and the Data Store Memory
block or Simulink.Signal object.
