Type for MATLAB array
The fundamental type underlying MATLAB® data. For information on how the MATLAB array works with MATLAB-supported variables, see MATLAB Data.
mxArray is a C language opaque type.
All C MEX-files start with a gateway routine, called mexFunction,
which requires mxArray for both input and output
parameters. For information about the C MEX-file gateway routine,
see Components of MEX File.
Once you have MATLAB data in your MEX-file, use functions
in the Matrix Library to manipulate the data, and functions in the
MEX Library to perform operations in the MATLAB environment.
You use mxArray to pass data to and from these
functions.
Use any of the mxCreate* functions to create
data, and the corresponding mxDestroyArray function
to free memory.
The header file containing this type is:
#include "matrix.h"
See the
following examples in matlabroot/extern/examples/mx.
For information about data in MATLAB language scripts and functions, see Data Types.
For troubleshooting mxArray errors
in other MathWorks products, search the documentation for that product,
or see MATLAB Answers™ topic "Subscripting
into an mxArray is not supported".
