Call MATLAB from C++ - MATLAB & Simulink (original) (raw)
Main Content
Run MATLAB® code from C++ programs, with object-oriented programming support and asynchronous execution
The MATLAB Engine API for C++ provides an interface between the C++ programming language and MATLAB. This API enables C++ programs to launch MATLAB, evaluate MATLAB functions with arguments, and exchange data between MATLAB and C++ programs. Supported operations include:
- Start MATLAB.
- Connect to a MATLAB shared session on the local machine.
- Call MATLAB functions with input arguments passed from C++ and output variables returned from MATLAB.
- Evaluate MATLAB statements in the MATLAB base workspace.
- Pass variables from C++ to MATLAB and from MATLAB to C++.
To get started, see Set Up C++ Development Environment.
The MATLAB Engine API for C++ uses the MATLAB Data API for C++, which provides a way for applications running outside of MATLAB to work with MATLAB data through a language-neutral interface. The engine API also provides a strongly typed interface that enforces a strict data type mapping between MATLAB and C++. You can use this strongly typed interface to call MATLAB functions and classes by their MATLAB names in C++ as if they were native C++ functions and classes. For an example, see Integrate Strongly Typed MATLAB Data in C++ Application.
