About mwArray

Use the mwArray class to pass input/output arguments to MATLAB Compiler generated C++ interface functions. This class consists of a thin wrapper around a MATLAB array. As explained in further detail in the MATLAB documentation, all data in MATLAB is represented by matrices (in other words, even a simple data structure should be declared as a 1-by-1 matrix). The mwArray class provides the necessary constructors, methods, and operators for array creation and initialization, as well as simple indexing.

Note   Arithmetic operators, such as addition and subtraction, are no longer supported as of Release 14.
