I am trying to execute some example code from a MATLAB toolkit, \'oscmex\'. This toolkit allows for communication using the OSC protocol over MATLAB. I presume this question
I took a look at your OSC Toolkit. It seems they have been compiled by MATLAB mex. But, it is not mentioned for which kind of architecture they have been built. You can type mexext at MATLAB command prompt to find the extension for your MATLAB mex files. Then, change the DLL extensions to the given extension. If the original mex is compatible with your matlab, the DLL can be easily accessed by MATLAB. Just make sure to add the folder to your MATLAB path.
