MATLAB Data API for C++

Use the MATLAB® Data API to read and write MATLAB data from C++ programs

The MATLAB Data API provides a way for applications running outside of MATLAB to work with MATLAB data through a MATLAB-neutral interface. The API uses modern C++ semantics and design patterns and avoids data copies whenever possible by using MATLAB copy-on-write semantics.

Note

The MATLAB Data API supports modern C++ features and is not compatible with the C Matrix API. You cannot mix functions from the MATLAB Data API with those in the C Matrix API and C MEX API in a MEX file. Likewise, you cannot mix MATLAB Data API functions with functions in the C Engine API, described in Call MATLAB from C, or the C MAT-File API, described in Write C Programs to Read MAT File Data.
