Writing the Driver Application

Note Due to name mangling in C++, you must compile your driver application

with the same version of your third-party compiler that you use to compile

your C++ shared library.

This e xample uses a C++ v ersio n of the matrixdriver application,

matrixdriver.cpp. In the C++ v ersion, arrays are represented by objects

of the class

mwArray.EverymwArray class object contains a pointer to a

MATLAB array structure. For this reason, the attributes of an

mwArray object

are a superset of the attributes of a MATLAB array. Every MATLAB array

contains information about the size and shape of the array (i.e., the number

of rows, columns, and pages) and either one or two arrays of data. The first

array stores the real part of the array data and the second array s tores the

imaginary part. For arrays with no imaginary part, the second array is not

present. The data in the array is arranged in column-major, rather than

ro w- ma jor, order.
