Test Your Build Environment
To test your installation and environment, build the
arrayProduct.cpp MEX file that is included with MATLAB®. The source code for this MEX example is in subfolders of
sure that you have a MATLAB-supported compiler installed.
To build a code example, first copy the file to a writable folder on your path. You
can use the
arrayProduct.cpp example to test your build
environment. This MATLAB command copies the
arrayProduct.cpp file to your
To set up and build MEX files, use the
mex command. First set up the environment for C++.
mex -setup C++
Select the installed compiler that you want to use when prompted by the
mex setup script. Then call the
mex command to build your program. Ensure that C++ MEX supports the
compiler you select. For an up-to-date list of supported compilers, see Supported and Compatible Compilers.
mex command saves the callable file in the current
arrayProduct MEX function using the file name without the
extension. Pass a scalar multiplier and an array of doubles as arguments. The MEX
function multiplies each element in the input array by the multiplier and returns the
