Using the C++ Math Library

Importing and Exporting MAT-File Data 

The MATLAB C++ Math Library provides two functions, load() and save(), that let you import mwArray variables from a MAT-file and export mwArray variables to a MAT-file. Because MATLAB also reads and writes MAT-files, you can use load() and save() to share data with MATLAB applications or with other applications developed with the MATLAB C++ or C Math Library.

A MAT-file is a binary, machine-dependent file. However, it can be transported between machines because of a machine signature in its file header. The MATLAB C++ Math Library checks the signature when it loads variables from a MAT-file and, if a signature indicates that a file is foreign (file was saved on a different architecture than the one on which it is being loaded), performs the necessary conversion.

Note    The MATLAB C++ Math Library functions save() and load() implementations do not support all the variations of the MATLAB load and save syntax. In addition, the load() and save() implementations do not conform to the standard MATLAB C++ Math Library calling convention: they accept arguments that are not of type mwArray or mwArray *. The load() routine also allows output and input arguments to be interspersed.
