MATLAB Classes
You can use MATLAB classes, including value classes, handle classes, and System objects, in a MATLAB Function block. To learn more about value and handle classes in MATLAB, see Comparison of Handle and Value Classes. To learn more about System objects, see What Are System Objects?.
You must be aware of certain usage notes and limitations when using classes in a MATLAB Function block.
Blocks
| MATLAB Function | Include MATLAB code in Simulink models |
| MATLAB System | Include System object in model |
Topics
- Class Limitations for Code Generation (MATLAB Coder)
Adhere to code generation restrictions when you use classes in MATLAB code for code generation.

Special considerations for using System objects in code generated from MATLAB.
- Code Generation for Handle Class Destructors (MATLAB Coder)
Use a handle class destructor in MATLAB code intended for code generation.
- Generate Code for MATLAB Functions That Use Value Classes (MATLAB Coder)
Use a value class in MATLAB code intended for code generation.
- Generate Code for MATLAB Functions That Use Handle Classes (MATLAB Coder)
Use a handle class in MATLAB code intended for code generation.

Use a singleton handle class in MATLAB code for code generation.
Troubleshooting
Resolve Error: Handle Object Referenced by Persistent Variable (MATLAB Coder)
Troubleshoot error when using a persistent handle object.
Resolve Error: Nontunable Property Cannot Be Defined by Subscripted Assignment (MATLAB Coder)
Troubleshoot code generation failure when a System object uses a structure.
Resolve Error: Class Properties Must Be Fully Defined Before Use (MATLAB Coder)
Troubleshoot code generation error when class properties are not defined before use.
Resolve Error: Cannot Reference Handle Object Outside of Loop (MATLAB Coder)
Troubleshoot error when creating or allocating a handle object inside a
for-loop.
Resolve Error: Class Does Not Have Property (MATLAB Coder)
Troubleshoot issues when you assign a value to a property of a handle class that is returned by a method.
Resolve Error: Passing by Reference Not Supported for Some Properties (MATLAB Coder)
Troubleshoot error when you use certain types of properties with
coder.ref, coder.rref, or
coder.wref.
Resolve Error: coder.varsize Not Supported for Class Properties (MATLAB Coder)
Troubleshoot code generation error when using coder.varsize
with properties of a MATLAB class.
