Directly call Python® functionality from MATLAB®

You can access Python libraries directly from MATLAB by adding the py. prefix to the Python name. See Access Python Modules from MATLAB - Getting Started. For example:

py.list({'This','is a','list'})      % Call built-in function list
py.textwrap.wrap('This is a string') % Call wrap function in module textwrap

You can execute Python statements in the Python interpreter directly from MATLAB using the pyrun or pyrunfile functions. For example:

pyrun("l = ['A','new','list']")  % Call list in Python interpreter

For more information, see Directly Call Python Functionality from MATLAB.

If instead you want to call MATLAB functions from Python applications, see Call MATLAB from Python for more information.

Passing Data

• MATLAB to Python Data Type Mapping
  How MATLAB converts MATLAB data into compatible Python data types.
• Access Elements in Python Container Types
  A Python container is typically a sequence type (list or tuple) or a mapping type (dict).
• Pass Python Function to Python map Function
  This example shows how to display the length of each word in a list.

Troubleshooting

Determine if Error is Python or MATLAB Error

Tips to determine if an error originates in Python or MATLAB code.

• Unable to resolve the name py.myfunc
• Debug Python Code Using MATLAB Interface

Limitations to Python Support

Python features not supported in MATLAB.

Handle Python Exceptions

MATLAB catches exceptions thrown by Python and converts them into a matlab.exception.PyException object.

Troubleshooting Matrix and Numeric Argument Errors

Error might be caused by input array with more than one non-singleton dimension.
