Supported Features
Properties
Classdef properties are supported but not all attributes are implemented.
| Attribute | Support | Notes |
|---|---|---|
| AbortSet | No | Property does not exist. |
| Abstract | Yes | |
| Access | Partial | |
| Constant | Yes | |
| Dependent | Partial | |
| GetAccess | Partial | |
| GetObservable | No | Property exists but is not used. Requires events and listeners to be implemented in order to work properly. |
| Hidden | Yes | |
| NonCopyable | No | Property does not exist. |
| SetAccess | Partial | |
| SetObservable | No | Property exists but is not used. Requires events and listeners to be implemented in order to work properly. |
| Transient | No | Property exists but is not used. |
Methods
Classdef methods are supported but not all attributes are fully implemented.
| Attribute | Support | Notes |
|---|---|---|
| Abstract | Partial | See bug report #51377 |
| Access | Yes | |
| Hidden | Yes | |
| Sealed | Yes | |
| Static | Yes |
Features that are not implemented
