MATLAB: Where to obtain MX/MEX/MAT/Engine Libraries

MATLABmex

Hi,

I reading a few manuals regarding mex files and they have a lot of references for the libraries MX Library, MEX Library, MAT file Library and Engine Library.

Moreover, I need to obtain mex.h to modify and compile a cpp mex file I downloaded and I believe mex.h is included in one of those libraries.

Where can I download those libraries? Do I need to purchase them? Can someone please explain if those packages are indeed critical to mex development and how?

Thanks, Gil.

The libraries ship with MATLAB. You should compile your MEX-file using the MATLAB mex utility, which will automatically resolve those libraries for you.

Creating a C shared library with MEX-files is analogous to creating one with MATLAB files as in the example located in the MATLAB Compiler Documentation:

http://www.mathworks.com/access/helpdesk/help/toolbox/compiler/

In step 2 of Building the Shared Library, instead of MATLAB files, you can specify MEX-files. For example, if you have MEX-files named mex1.dll and mex2.dll on Windows, you would execute the following command:

 mcc -B csharedlib:sharedlibname mex1.dll mex2.dll

where "sharedlibname" is the name of the library you wish to create. This command would generate a file sharedlibname.dll that contains functions of mex1 and mex2.
