==Synopsis==
This is an example that controlling BCI2000 under Windows from MATLAB.
Matlab is able to interface with dynamic libraries(.dll,.so,.dylib) if a header file is available.(http://www.mathworks.com/help/matlab/using-c-shared-library-functions-in-matlab-.html). Thus we can load the [[Programming Reference:BCI2000Remote Class#BCI2000RemoteLib|BCI2000RemoteLib]] library by specifying <tt> prog/BCI2000RemoteLib.dll</tt> as C shared library and <tt>src/core/Operator/BCI2000Remote/BCI2000RemoteLib.h</tt> as header file when calling MATLAB's <tt>loadlibrary</tt> function. When using BCI2000RemoteLib this way, your MATLAB code will run on all platforms supported by BCI2000, and no COM registration will be required on Windows systems.
