mex_array_product.cpp

Go to the documentation of this file.

//------------------------------------------------------------------------------
/* This file illustrates how to construct a simple C++ MEX-File with
 * easyLink.
 *
 * Multiplies an input scalar times a 1xN matrix and outputs a 1xN matrix
 *
 * The calling syntax is:
 *
 *     outMatrix = mex_array_product(multiplier, inMatrix)
 *
 * To compile this C++ MEX-File, enter the following command in MATLAB:
 *
 *     >>make mex_array_product.cpp
 *

// The possible types of the inputs are:
//     * 1 for real parameters (scalar or array, use -1 as size to specify
//          a dynamically dimensioned array)
//     * 2 for literal string parameters
//     * 3 for literal identifiers of MATLAB variables
