Call Python from MATLAB

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.
