mexArrayProduct.cpp

/* 
 * This file illustrates how to construct a simple C++ MEX-File with
 * EasyLink.
 *
 * The function multiplies an input scalar times an input NxM array and outputs 
 * a NxM array.
 *
 * The calling syntax is:
 *
 *     outArray = mexArrayProduct(multiplier, inArray)
 *
 * To compile this C++ MEX-File, enter the following command in MATLAB:
 *
 *     >>make mexArrayProduct.cpp
 *
