C type for MATLAB array
The fundamental type underlying MATLAB® data.
mxArray is a C language opaque type. The header
file containing this type is:
For information on how
mxArray works with MATLAB-supported variables, see MATLAB Data.
All C MEX files start with a gateway routine, called
mxArray for both input and output parameters. For
information about the C MEX file gateway routine, see Components of C MEX File.
Once you have MATLAB data in your MEX file, use functions in the C Matrix API to manipulate the
data and functions in the C MEX API to perform operations in the MATLAB environment. Use
mxArray to pass data to and from these
See these examples in
In Simulink® S-functions, do not store
mxArray pointers in any S-function block state that persists
after the MEX function finishes. An output
temporary scope and is automatically destroyed at the end of the MEX function
For information about data in MATLAB language scripts and functions, see Data Types.

products, search the documentation for that product.
