通过 System object 实现模块
MATLAB System 模块使用 System object 在 Simulink 中实现 MATLAB® 算法。在开始使用 MATLAB System 模块之前,必须有某模块与 System object 关联。System object 是一种特殊的 MATLAB 类,它们专为动态系统的实现和仿真而设计。有关实现和创建 System object 的信息,请参阅创建 System object。

主题
- MATLAB System 模块
使用 System object 实现您自己的算法。
- 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 with Other Blocks
Share data between MATLAB System and other blocks using the
global
keyword and the Data Store Memory block orSimulink.Signal
object. - Call Python Function Using MATLAB Function and MATLAB System Block
This example shows how to call a Python® function in Simulink® that sorts random numbers using a Python® sorting function and two different blocks: the MATLAB Function block and MATLAB System block.
- Mapping System Object Code to MATLAB System Block Dialog Box
The System object source code controls the appearance of the block dialog box.
- Simulation Modes
You can use a 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 with Other Blocks
Share data between MATLAB System and other blocks using the
global
keyword and the Data Store Memory block orSimulink.Signal
object. - Considerations for Using System Objects in Simulink
Consider these guidelines when working with variable-size signals, tunable parameters, and For Each subsystems.
