Create your CMEX function

Create cmex function.

A CMex function is a DLL that requires some cosmetics to be compatible with MATLAB. This section describes how to create this DLL using Visual Studio IDE, assuming you are familiar with this tool. If you are using other compiler, follow the instructions given ant translate it for your compiler : method may be similar.

You can also look at sample [MarilouInstallDir]\Samples\external\MATLAB\Interface\Robot\VCxxx projects.

Create project and files:

(assumes your DLL is called Robot.dll)

Open Visual Studio and create a new Project Win32 DLL (called Robot).

Create a Robot.def file that exports the MATLAB mexFunction

LIBRARY Robot.DLL
EXPORTS mexFunction

Create a CPP file that contains your cmexfunction:

void mexFunction( int nlhs, mxArray *plhs[],int nrhs, const mxArray *prhs[])
{
}

Project settings:

These settings assume $(MATLABDIR) is registered in your system. If not, replace this variable using the MATLAB absolute path.

C++ compiler options	Description/Value
additional include directories	$(MARILOU_INSTALL_DIR_SDKS)\Moda\Includes $(MATLABDIR)\extern\include
Precompiled headers	'No'
Code Generation	use runtime DLL Multitheaded (and Debug Multithreaded DLL for the debug mode)

Linker options	Description/Value
additional libraries search path	$(MARILOU_INSTALL_DIR_SDKS)\Moda\Libs $(MATLABDIR)\extern\\lib\win32\microsoft\msvc60 (change msvc60 according to your compiler version)
Additional libraries for MATLAB	libmx.lib libmex.lib libmat.lib
Additional libraries for MODA	xklib-x86-win-CCC.lib moda-x86-win-CCC.lib wsock32.lib (where CCC is your compiler)
Module definition file	set the file.def created at the start of your project

Using Wizard:

cmex function can be created automatically using the MATLAB Wizard.
