CallMATLAB从Python

Write Python^®programs that work with MATLAB^®

The MATLAB Engine API for Python provides a package for Python to call MATLAB as a computational engine. The engine supports the reference implementation (CPython).For supported version information, seeVersions of Python Compatible with MATLAB Products by Release.

To install and start the engine, see开始使用Python的Matlab Engine API.
To call Python functions from MATLAB, see从Matlab致电Python.

Engine applications require an installed version of MATLAB; you cannot run the MATLAB engine on a machine that only has the MATLAB Runtime.
