Limitations to Python Support
|Features Not Supported in MATLAB®
Closing the Python® interpreter while running MATLAB with in-process execution mode.
Saving (serializing) Python objects into a MAT-file.
Interactive Python help (calling
Accessing static properties of a Python class.
MATLAB class inheritance from a Python class.
Customized (dynamic) attribute access.
Nested Python classes.
Modules that start MATLAB in a separate process, for example, the
Modules that read
Dynamically generated Python classes.
Dynamically attaching new object attributes. Instead, use
Class names or other identifiers starting with an underscore
Python modules generated by the MATLAB Compiler SDK™ product.
Python code using Cocoa (AppKit) for user interfaces on macOS platforms.
The size of variables passed between Python and MATLAB is limited to 2 GB when you call a Python function out-of-process. This limit applies to the data plus supporting information passed between the processes.
Python classes defined using
pyrunfile cannot be modified if you return an instance of the class to MATLAB. If you need to change class definitions, restart the interpreter session:
Alternatively, restart MATLAB for
pyrunfile functions do not support classes with local variables that are initialized by other local variables through methods. For such usage, create a module and access it using the
Unsupported MATLAB Types
These MATLAB types are not supported in Python.
